    Sparganosis is caused by plerocercoid larvae of the Pseudophyllidea tapeworms of the genus Spirometra. Though prevalent in East Asian and south east Asian countries like China, Japan, Korea, Taiwan, Vietnam, Thailand; yet very few cases are reported from India. We report a case of migrating sub-conjunctival ocular sparganosis mimicking scleritis which later on developed into orbital cellulitis from Dibrugarh, Assam, North-eastern part of India. This case is reported for its rarity. PMID:25709957

    Human sparganosis is a food borne zoonosis caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms of the genus Spirometra. Human infections are acquired by ingesting the raw or undercooked meat of snakes or frogs, drinking untreated water, or using raw flesh in traditional poultices. More than 1600 cases of sparganosis have been documented worldwide, mostly in east and southeast Asia. Sporadic cases have been reported in South America, Europe, and Africa, and several cases have been described in travellers returning from endemic regions. Epidemiological data suggest that the increased effect of sparganosis on human health is because of greater consumption of raw meat of freshwater frogs and snakes. This Review provides information about the Spirometra parasites and their lifecycles, summarises clinical features, diagnosis, and treatment of human sparganosis, and describes geographical distribution and infection characteristics of Spirometra parasites in host animals.

    Humans are known to serve as the secondary intermediate host for some larval forms of canine or feline tapeworms. Sparganosis is caused by plerocercoid larva of Spirometra of which there are three main species; Spirometra mansoni (or Spirometra erinaceieuropaei), Spirometra mansonoides and Spirometra proliferum. A one-and-half-year-old patient presenting with febrile illness was diagnosed radiologically as a case of liver abscess. The aspirate from the abscess cavity had a thin thread-like worm which was identified as a larval stage of Pseudophyllidea that was further confirmed as belonging to genus Spirometra. Aspiration of the worm and antiparasitic therapy with metronidazole led to complete recovery. Reports of sparganosis from Indian subcontinent are scanty and these cases had involvement of brain, kidney and eye. To the best of our knowledge this is the first case of hepatic sparganosis from India. PMID:23220827

    Sparganosis is a very rare parasitic infection in various organs caused by the larvae of tapeworms called spargana. The larva usually lodges in the central nervous system (CNS) and the orbit. However, lumbar spinal canal involvement, as noted in the present case, is extremely rare. We report a rare case of disseminated CNS sparganosis involving the brain and spinal canal and review the literature. A 54-year-old man presented with progressive low back pain and neurological deficit at the lumbosacral level for 2 months. Imaging indicated arachnoiditis and an abnormal lesion at the L4-5 vertebral level. The patient underwent laminectomy of the L4-5 with lesionectomy and lysis of adhesions between the nerve roots. Microscopic examination indicated sparganum infection. Further brain imaging revealed evidence of chronic inflammation in the left parieto-occipital area without evidence of live parasites. In addition, an ophthalmologist reported a nonactive lesion in the right conjunctiva. The patient recovered well after surgery, although he had residual back pain and bladder dysfunction probably due to severe adhesion of the lumbosacral nerve roots. CNS sparganosis can cause various neurological symptoms similar to those of other CNS infections. A preoperative enzyme-linked immunosorbent assay is helpful for diagnosis, especially in endemic areas. Surgical removal of the worm remains the treatment of choice.

    We present a case of aggressive angiomyxoma of the vulva. The patient presented with a persistent, enlarging vulvar mass, initially misdiagnosed as a Bartholin gland cyst. The patient underwent wide local excision, which resulted in total resection of the mass. Final pathology was consistent with aggressive angiomyxoma, a rare soft tissue tumor with a predilection for the female pelvis. Though rare, it is important to consider in the differential diagnosis of a pelvic mass, given the locally aggressive nature of this tumor and propensity for recurrence.

    The authors report the case of a 6-year-old boy with cerebral sparganosis due to infection with a plerocercoid tapeworm larva of Spirometra mansoni. Magnetic resonance imaging revealed an area of irregular long T2 signal in the right frontal lobe. When compared with images obtained 2 years earlier, the lesion appeared to have migrated into the parietal lobe. During surgery for the removal of a granuloma, the parasite was discovered and excised. Following surgery, the patient's neurological deficits markedly improved. The authors review the pathological and imaging features of cerebral sparganosis.

    Human sparganosis is one of the neglected diseases but important food-borne parasitic zoonoses. The disease is caused by larvae (spargana) of diphyllobothriidean tapeworm. Here, we describe nine cases of human sparganosis, caused by Spirometra erinaceieuropaei in a hospital in Thailand during 2001–2012. Clinical characteristics, treatment, and outcome of cases were revealed. Diagnosis and identification of causative parasite species was made by histopathological investigations followed by a polymerase chain reaction-based molecular method using formalin-fixed paraffin embedded tissues. The DNA samples were extracted from tissues and a partial fragment of cytochrome c oxidase subunit 1 (cox1) gene was amplified for the detection of parasitic DNA. Infection could be prevented by increasing activities on health communication by responsible public health agencies. PMID:24842879

    Epithelioid sarcoma of the vulva is an extremely rare and aggressive tumor. This tumor most commonly occurs on the labia majora in women of reproductive age. The molecular pathogenesis remains largely unknown. Only 20 cases of vulvar epithelioid sarcoma have been reported to date and more than half have had poor outcomes. We report a successfully treated case of vulvar epithelioid sarcoma in a 33-year-old woman. We performed a radical vulvectomy with flap reconstruction. Three years after surgery, the patient remains well, showing no evidence of recurrence. Early tissue diagnosis of vulvar epithelioid sarcoma is essential because this tumor can be clinically misdiagnosed as a benign lesion. Gynecologists should be aware of this rare tumor variant and carefully plan the treatment. © 2011 The Authors.

    A 50-year-old grandmultiparous petty trader presented in the gynaecological unit of the University of Uyo Teaching Hospital with a painless groin swelling of 8 years’ duration, which had progressively increased in size. She had received several concoctions from a traditional healer who also made several incisions on her thighs and inguinal region. On examination, there were multiple scarification marks in the axilla, inguinal region and medial aspects of both thighs. There was a very huge, firm, non-tender mass involving the right vulva and measuring 40 by 35 cm (figure 1). The vaginal orifice was deviated to the left by the mass, the uterus was normal size and the adnexa were normal. She had an excision biopsy under general anaesthesia (figure 2) and the histology confirmed fibroma of the vulva (figure 3). She had an uneventful postoperative period and the wound healed well with good cosmetic results. Figure 1A huge vulva mass. Figure 2The vulva after the mass has been excised.

    Acantholytic dermatosis of the vulva is a rare condition, presenting with papular eruption in the genital area without history of Darier disease or Hailey-Hailey disease. We report a case with a papular pruritic eruption in the region of the vulva, coalescing into plaques. Biopsy specimen showed irregular acanthosis with an area of split-like bullous formation in the deeper part of the epidermis, as well as acantholytic cells, marked hypergranulosis and hyperkeratosis, compatible with the rare diagnosis of acantholytic dermatosis of the vulva. We review the clinical and histological characteristics of this uncommon disease.

    Despite global eradication efforts, female genital cutting is still deep routed practice in some parts of Asia and East Africa. The crude and unscientific natures of the practice lead to many complications. Epidermoid inclusion cysts of the vulva are one of the late complications of female genital cutting and typically present as painless cystic swellings. But clinical presentation as 'stone' containing, hard vulvar mass is reported only once in the literature and presentation with acute vulvar pain has never been documented. A 21 yrs old, Ethiopian, unmarried, lady presented with sever acute vulvar pain, discharge, and a stony hard vulvar swelling 13 years after type-III female genital cutting (infibulation). Surgical excision of the cyst, which contained two 'stones' inside it, and defibulation were done. Histopathology confirmed calcified, keratinizing epidermoid inclusion cyst of the vulva. Clinicians, in areas where female genital cutting is prevalent, should be aware of such unusual late vulvar complication of the practice which might be misdiagnosed for other solid vulvar swellings and be familiar with the appropriate management.

    To diagnose 10 cases of clinically suspected cases of sparganosis mansoni by pathogen identification. In the period from August 2009 to August 2011, 10 biopsy specimens were obtained from 10 patients of four hospitals to identify the pathogen. Among the 10 cases, 4 cases showed abdominal subcutaneous mass, 3 showed eyelid swelling, 1 displayed brain lesions, 1 showed pulmonary mass, and 1 showed pleural effusion. There was one parasite each from three patients with eyelid swelling, and one patient with abdominal subcutaneous mass, which were observed by naked eye and microscope morphologically and histologically. Specimens from other six cases were examined by microscope after paraffin embedding, sectioning, and HE staining. For further identification, the parasite biopsy tissue specimens were detected by immunohistochemistry with Sparganum mansoni-immunized rabbit serum as the primary antibody. Three intact worms, from three patients with eyelid swelling, showed typical S. mansoni morphological characteristics. One residue parasite from the abdominal subcutaneous mass showed network structures and full of calcareous corpuscles in the body under microscope same as that of S. mansoni. The histological structure in three of the six sections showed typically the body wall with folds, which was dense, thick and deeply eosine stained, part of the tegument outside was covered by micro-hairs. In the worm body there was net-like loose structure and calcareous corpuscles without cavity. The structure of the other three worm sections was atypical. The six worm sections were positive by immunohistochemical detection. The 10 clinically suspected cases are diagnosed as sparganosis mansoni.

    Most malignant mesotheliomas are pleural; they rarely occur within the peritoneum and their location in the vulva is exceptional. A case of a malignant mesothelioma of the vulva is reported in a 47-year-old woman. The patient was operated for a tumour of the vulva. The preoperative diagnosis was that of a cyst of the Bartholin's gland or a fibroma. The microscopic and immunohistochemical exam confirmed the diagnosis of a biphasic malignant mesothelioma of the vulva. The computed tomography scan of the chest and the abdomen was normal. A local recurrence of the tumour occurred in spite of the postoperative radiotherapy. Our objective about this particular case is to discuss the clinical and pathologic aspects and the diagnostic problems of this exceptional tumour of the vulva.

    Primary extraskeletal myxoid chondrosarcoma (EMC) of the vulva is extremely rare. There is little available information about the biological behavior and treatment strategy for primary EMC of the vulva. We report a rare case of primary EMC of the vulva treated surgically. A 24-year-old Japanese woman had demonstrated a small and elastic mass of the vulva and underwent enucleation of the mass at a previous hospital, but a definitive histopathological diagnosis was not obtained. Therefore, the patient was referred to our hospital for further evaluation and treatment. We histopathologically diagnosed the tumor as primary EMC of the vulva and performed vulvectomy with vulvoperineal reconstruction. Microscopic examination of the resected specimens demonstrated residual tumor nodules of EMC. However, there were no viable tumor cells at the surgical margin. Approximately two years after wide local excision was performed, the patient is doing well and there is no apparent recurrence of EMC. © 2011 The Authors.

    The Caenorhabditis elegans vulva is induced by a member of the epidermal growth factor (EGF) family that is expressed in the gonadal anchor cell, representing a prime example of signaling processes in animal development. Comparative studies indicated that vulva induction has changed rapidly during evolution. However, nothing was known about the molecular mechanisms underlying these differences. By analyzing deletion mutants in five Wnt pathway genes, we show that Wnt signaling induces vulva formation in Pristionchus pacificus. A Ppa-bar-1/beta-catenin deletion is completely vulvaless. Several Wnt ligands and receptors act redundantly in vulva induction, and Ppa-egl-20/Wnt; Ppa-mom-2/Wnt; Ppa-lin-18/Ryk triple mutants are strongly vulvaless. Wnt ligands are differentially expressed in the somatic gonad, the anchor cell, and the posterior body region, respectively. In contrast, previous studies indicated that Ppa-lin-17, one of the Frizzled-type receptors, has a negative role in vulva formation. We found that mutations in Ppa-bar-1 and Ppa-egl-20 suppress the phenotype of Ppa-lin-17. Thus, an unexpected complexity of Wnt signaling is involved in vulva induction and vulva repression in P. pacificus. This study provides the first molecular identification of the inductive vulva signal in a nematode other than Caenorhabditis.

    Primary vulva malignancy is a rare gynecologic malignancy. Most of them are squamous cell carcinomas and adenocarcinomas are much less common. Intestinal type is a rare variant of primary adenocarcinoma of the vulva. It histologically resembles mucinous colonic carcinomas. Origin from cloacal remnants has been suggested but remains speculative. A 64-year-old woman was referred to our clinic with a 1-month history of an itching vulva mass. An incisional biopsy was performed at other hospital and disclosed adenocarcinoma of intestinal type. Extensive workups were performed to detect other underlying carcinomas but revealed nothing abnormal. She underwent wide local excision without lymph node dissection for a primary vulva carcinoma. She received no adjuvant therapy and has been free from recurrent disease for 12 months after surgery. The authors report a rare case and review the relevant literature. PMID:28791269

    Plastic surgery of the vulva for aesthetic reasons is recently gaining popularity in the Western world, as well as in Israel. There are different methods of executing these operations with no meaningful difference in the surgical results and the satisfaction of the patients. There are also more complicated plastic operations, in which the vulva is involved. These are performed in cases of pseudohermaphroditism, various states of intersex, sex change operations and developmental defects of the genitor-urinary systems. These are considered successful procedures. Furthermore, the issue of the illegal mutilation surgery of the external female genitalia, on religious or cultural background, is mentioned. All the above-mentioned types of operations involving the vulva are discussed.

    Primary breast cancer fairly infrequently occurs in ectopic breast tissue, and primary ectopic breast cancer of the vulva is particularly rare. Only 26 cases have been published in the English-language literature, and there has been no report of primary breast carcinoma of the vulva in Japan. We report a rare case of primary ectopic breast cancer of the vulva that was treated with local excision of the vulva and sentinel lymph node biopsy (SLNB). The patient was a 72-year-old woman who had noticed a right vulvar tumor 10 years earlier. The tumor was excised by the Department of Plastic Surgery of our hospital. The histology of the vulvar tumor revealed an invasive ductal carcinoma of the breast, and immunohistochemical staining of the vulvar specimen showed the tumor cells to be 100% estrogen-receptor-positive and 100% progesterone-receptor-positive. All margins of resection were positive for neoplastic involvement. An additional local excision of the vulva and right inguinal SLNB were performed in our department. The intraoperative frozen section was negative for metastasis, and lymph node dissection was not performed. The final pathology was negative for residual disease, and a partially normal ductal component was present. Adjuvant hormonal therapy with an aromatase inhibitor was indicated post-operatively. The patient was asymptomatic and free of detectable disease at a 6-month follow-up. Due to the rarity of this diagnosis, there are no established guidelines for treatment. Although cases in which SLNB was performed are rare, we consider SLNB to be an effective alternative to inguinal node dissection for ectopic primary breast cancer of the vulva.

    To report the case of a patient with a large and symptomatic vulvar lesion, necessitating surgical excision. We report the case of a 57-year-old postmenopausal woman with a 6-month history of an enlarging vulvar lesion associated with vulvar pruritus. On examination, a pedunculated 7 × 5 × 4-cm soft tissue mass attached to the left labium majus was noted. Surgical excision was performed and histopathologic evaluation revealed variably dilated, submucosal vessels with thick muscular walls and intimal thickening, but without endothelial atypia or multilayering. These findings were consistent with a final diagnosis of arteriovenous malformation of the vulva. Given the complex anatomy of the vulva, the differential diagnosis for vulvar vascular lesions can be challenging. Hence, surgical excision and histopathologic evaluation become imperative to distinguish them from other dermatologic and neoplastic conditions of the vulva.

    Understanding how cells move, change shape, and alter cellular behaviors to form organs, a process termed morphogenesis, is one of the great challenges of developmental biology. Formation of the Caenorhabditis elegans vulva is a powerful, simple, and experimentally accessible model for elucidating how morphogenetic processes produce an organ. In the first step of vulval development, three epithelial precursor cells divide and differentiate to generate 22 cells of 7 different vulval subtypes. The 22 vulval cells then rearrange from a linear array into a tube, with each of the seven cell types undergoing characteristic morphogenetic behaviors that construct the vulva. Vulval morphogenesis entails many of the same cellular activities that underlie organogenesis and tissue formation across species, including invagination, lumen formation, oriented cell divisions, cell–cell adhesion, cell migration, cell fusion, extracellular matrix remodeling, and cell invasion. Studies of vulval development have led to pioneering discoveries in a number of these processes and are beginning to bridge the gap between the pathways that specify cells and their connections to morphogenetic behaviors. The simplicity of the vulva and the experimental tools available in C. elegans will continue to make vulval morphogenesis a powerful paradigm to further our understanding of the largely mysterious mechanisms that build tissues and organs. © 2012 Wiley Periodicals, Inc.

    Many women have doubts about the normality of the physical appearance of their vulvas. This study measured genital self-image in a convenience sample of college-educated women, and assessed whether exposure to pictures of natural vulvas influenced their genital self-image. Forty-three women were either shown pictures of natural vulvas (N = 29) or pictures of neutral objects (N = 14). Genital self-image was measured before and after exposure to the pictures and two weeks later. Sexual function, sexual distress, self-esteem and trait anxiety were measured to investigate whether these factors influenced genital self-image scores after vulva picture exposure. A majority of the participants felt generally positively about their genitals. Having been exposed to pictures of natural vulvas resulted in an even more positive genital self-image, irrespective of levels of sexual function, sexual distress, self-esteem and trait anxiety. In the women who had seen the vulva pictures, the positive effect on genital self-image was still present after two weeks. The results of this study seem to indicate that even in young women with a relatively positive genital self-image, exposure to pictures of a large variety of natural vulvas positively affects genital self-image. This finding may suggest that exposure to pictures of natural vulvas may also lead to a more positive genital self-image in women who consider labiaplasty.

    The appearance of the female external genitalia is key for understanding and diagnosing many diseases that women of all ages encounter. Alas, the normal appearance of the vulva is an elusive concept, scarcely represented in textbooks, and the growing number of vulvar cosmetic surgery calls for a review of the normal appearance of the vulva and its diversity. In this paper I will review vulvar embryology, anatomy, the current literature discussing vulvar appearance, and describe meticulous vulvar examination, including the diagnostic tools.

  9. Germ-line induction of the Caenorhabditis elegans vulva

    PubMed Central

    Thompson, Beth E.; Lamont, Liana B.; Kimble, Judith

    2006-01-01

    Development of the Caenorhabditis elegans vulva serves as a paradigm for intercellular signaling during animal development. In wild-type animals, the somatic gonadal anchor cell generates the LIN-3/EGF ligand to induce vulval fates in the underlying hypodermis, whereas FBF, FOG-1, and FOG-3 control germ-line development. Here we report that FBF functions redundantly with FOG-1 and FOG-3 to control vulval induction: animals lacking FBF and either FOG-1 or FOG-3 have multiple vulvae, the Muv phenotype. The fog; fbf Muv phenotype is generated by aberrant induction of vulval precursor cells (VPCs): in wild-type animals, three VPCs are induced to form a single vulva, but, in fog; fbf mutants, four or five VPCs are typically induced, resulting in ectopic vulvae. Laser ablation experiments and mosaic analyses demonstrate that the germ line is critical for the fog; fbf Muv phenotype. Consistent with that site of action, we detect FBF and FOG-1 in the germ line but not in the VPCs. The simplest interpretation is that FOG-1, FOG-3, and FBF act in the germ line to influence vulval fates. The LIN-3/EGF ligand may be the germ-line signal to the VPCs: the fog; fbf Muv phenotype depends on LIN-3 activity, and the lin-3 3′ UTR possesses an FBF binding element. Our findings reveal new insights into germ line-to-soma signals and the role of PUF proteins in animal development. PMID:16407099

  10. [Malignant vascular tumors of the vulva].

    Due to the increased vascularity as well as the unique anatomical structure, vascular lesions, which occur in the female reproductive system are common observed and diverse by their morphology. The majority of them are benign, including vascular malformations, lesions due to vascular hyperplasia, tumors with significant vascular component and others. Malignant vascular tumors are rare in the area of the vulva accounting about 1% of all vulvar lesions with vascular origin. Kaposi sarcoma, epithelioid hemangioepithelioma and epithelioid angiosarcoma have been reported with vulvar localization. With a view to their rare incidence, nonspecific clinical manifestation and aggressive behavior associated with high mortality, we present the most common malignant tumors of vascular origin arising in the vulva, as we emphasize on their epidemiology and clinical features, differential diagnosis and therapeutic algorithms for this rare type of malignancies.

    Perineal nodules occurring in male cyclists are reported in the literature, although the histologic features are not extensively documented. There has been little description of similar lesions in the female population. We describe 4 cases in which a vulval nodule or swelling developed in competitive female cyclists aged 15 to 45 years. The lesions were unilateral and occurred on the right or left labium majus (2 cases each). The histologic features were similar in all cases and consisted of a haphazard admixture of adipose tissue, variably cellular hyalinized tissue containing bland spindle-shaped fibroblasts, blood vessels, and nerve fibers. In some areas, thick cords of fibrous tissue imparted a keloid-like appearance. Other histologic features included plump mesenchymal cells with round or ovoid nuclei and abundant eosinophilic cytoplasm resulting in an epithelioid, plasmacytoid, or ganglion-like appearance (2 cases), a lymphocytic infiltrate around blood vessels (3 cases), foci of fat necrosis (1 case), and collections of elastic fibers (2 cases). One case recurred, the histologic features of the recurrent lesion being identical to the original. The overall morphologic appearances, especially in the cases with plump mesenchymal cells, bore some resemblance to proliferative fasciitis. Immunohistochemically, the cells were estrogen receptor positive and the plump mesenchymal cells were smooth muscle actin positive, in keeping with myofibroblasts. Desmin, S100, CD34, and HMGA2 were negative. Pathologists should be aware of this pseudoneoplastic lesion occurring on the vulva, which arises in a specific clinical setting and has the potential to be misdiagnosed as a variety of other mesenchymal lesions. We term this lesion as reactive fibroblastic and myofibroblastic proliferation of the vulva or "cyclist's nodule."

    Crohn's disease (CD) of the vulva is a rare, yet under recognized condition. Fistulae arising from the digestive tract account for the greater part of genital lesions in CD. However, cutaneous so-called metastatic lesions of the vulva have been reported in the literature. They are clinically challenging for gastroenterologists as well as for gynecologists, with numerous differential diagnoses, especially among venereal diseases, and require a multidisciplinary approach. The most frequently observed features of the disease are labial swelling, vulvar ulcers, and hypertrophic lesions. Biopsy samples for histological study are mandatory, in order to establish the diagnosis of vulvar CD. Treatment options include oral prolonged courses of metronidazole and systemic immunosuppressive therapy such as corticosteroids and azathioprine, with promising data published on the efficacy of infliximab. Surgery remains restricted to medical treatment failures or resection of unsightly lesions. Prospective studies or case series with long follow-up data are still missing to guide the treatment of this condition. © 2013. Published by Elsevier B.V. All rights reserved.

    Primary vulvar sarcomas are rare lesions of the lower genital tract. We report the case of a patient with a spindle cell sarcoma of the vulva. A 44-year-old woman presented with a painless vulvar mass. Vulvar biopsy demonstrated a spindle cell sarcoma with myofibroblastic differentiation. Pretreatment evaluation revealed no evidence of metastatic disease, and magnetic resonance imaging found no local masses. The patient underwent right radical vulvectomy with negative margins and tolerated the procedure well. Women undergoing gynecologic care should have routine evaluation of the vulva to detect these rare neoplasms.

    Malignant melanoma of the vulva in childhood is a rare neoplasm. Lichen sclerosus of the vulva in childhood is also a rare disease. The association of these two rare lesions in the vulva of young girls is extremely rare. We present a 10-year-old white girl with malignant melanoma associated with lichen sclerosus of the vulva. She had dark pigmentation of both the labia minora and posterior fourchette. The inner labia majora and fourchette showed whitish, glistening areas of skin. Histologic examination found mostly an in situ lentiginous/mucosal melanoma with focal invasion to a depth of 0.44 mm in the left upper labium majus. All specimens showed evidence of lichen sclerosus. Partial vulvectomy was performed, and no metastases were detected at the time of treatment. The patient has been disease free for the 12 months after treatment. It is critical for physicians to realize that melanoma can occur in children, and although rare, can occur in the vulva. We feel that lichen sclerosus in this instance may represent a pattern of host immune response to melanoma.

    The C. elegans hermaphrodite vulva is an established model system to study mechanisms of cell fate specification and tissue morphogenesis. The adult vulva is a tubular shaped organ composed of seven concentric toroids that arise from selective fusion between differentiated vulval progeny. The dorsal end of the vulval tubule is connected to the uterus via a multinucleate syncytium utse (uterine-seam) cell. The vulval tubule and utse are formed as a result of changes in morphogenetic processes such as cell polarity, adhesion, and invagination. A number of genes controlling these processes are conserved all the way up to human and function in similar developmental contexts. This makes it possible to extend the findings to other metazoan systems. Gene expression studies in the vulval and uterine cells have revealed the presence of regulatory networks specifying distinct cell fates. Thus, these two cell types serve as a good system to understand how gene networks confer unique cell identities both experimentally and computationally. This chapter focuses on morphogenetic processes during the formation of the vulva and its connection to uterus. PMID:23208727

    The painful, erythematous and eroded vulva often proves to be a diagnostic problem both clinically and histologically. Its differential diagnosis includes both non-neoplastic and neoplastic diseases like Bowen's disease and squamous cell carcinoma (SCC). We report the case of a 62-year-old woman diagnosed, after considerable delay, with Bowen's disease of the vulva that eventually progressed to invasive SCC, despite the treatment with imiquimod 5% cream. Our case indicates, on one hand, that dermoscopy could contribute to the accuracy of the pre-operative clinical diagnosis. On the other hand it confirms the fact that treatment of Bowen's disease of the vulva could be rather intriguing. Although imiquimod 5% cream is an effective, non-invasive treatment option for large lesions or poor healing sites, it should be administered with great consideration in carefully selected cases.

    To determine the proportion of children diagnosed with constipation assigned a significant alternative diagnosis within 7 days (misdiagnosis), if there is an association between abdominal radiograph (AXR) performance and misdiagnosis, and features that might identify children with misdiagnoses. We conducted a retrospective cohort study of consecutive children <18 years who presented to a pediatric emergency department in Toronto, between 2008 and 2010. Children assigned an International Statistical Classification of Diseases and Related Health Problems 10th Revision code consistent with constipation were eligible. Misdiagnosis was defined as an alternative diagnosis during the subsequent 7 days that resulted in hospitalization or an outpatient procedure that included a surgical or radiologic intervention. Constipation severity was classified employing text word categorization and the Leech score. 3685 eligible visits were identified. Mean age was 6.6 ± 4.4 years. AXR was performed in 46% (1693/3685). Twenty misdiagnoses (0.5%; 95% CI 0.4, 0.8) were identified (appendicitis [7%], intussusception [2%, bowel obstruction [2%], other [9%]). AXR was performed more frequently in misdiagnosed children (75% vs 46%; P = .01). These children more often had abdominal pain (70% vs 49%; P = .04) and tenderness (60% vs 32%; P =.01). Children in both groups had similar amounts of stool on AXR (P = .38) and mean Leech scores (misdiagnosed = 7.9 ± 3.4; not misdiagnosed = 7.7 ± 2.9; P = .85). Misdiagnoses in children with constipation are more frequent in those in whom an AXR was performed and those with abdominal pain and tenderness. The performance of an AXR may indicate diagnostic uncertainty; in such cases, the presence of stool on AXR does not rule out an alternative diagnosis. Copyright © 2014 Mosby, Inc.

    2012-04-01

    The Caenorhabditis elegans vulva has served as a paradigm for how conserved developmental pathways, such as EGF-Ras-MAPK, Notch and Wnt signaling, participate in networks driving animal organogenesis. Here, we discuss an emerging direction in the field, which places vulva research in a quantitative and microevolutionary framework. The final vulval cell fate pattern is known to be robust to change, but only recently has the variation of vulval traits been measured under stochastic, environmental or genetic variation. Whereas the resulting cell fate pattern is invariant among rhabditid nematodes, recent studies indicate that the developmental system has accumulated cryptic variation, even among wild C. elegans isolates. Quantitative differences in the signaling network have emerged through experiments and modeling as the driving force behind cryptic variation in Caenorhabditis species. On a wider evolutionary scale, the establishment of new model species has informed about the presence of qualitative variation in vulval signaling pathways. Copyright © 2012 Elsevier Ltd.

    Papular acantholytic dyskeratosis (PAD) of the vulva is a rare, chronic disorder first described in 1984. It presents in young women as white to skin-coloured smooth papules over the vulva, which are persistent but asymptomatic. Histologically, there is hyperkeratosis and focal parakeratosis with acantholytic and dyskeratotic cells forming corps ronds and grains, placing PAD within Ackerman's spectrum of focal acantholytic dyskeratoses with Hailey-Hailey disease (HHD) and Darier disease. There have been 17 previous reports of PAD of the vulva, to our knowledge. Only one demonstrated a familial pattern, and none of the cases was associated with a family history of HHD. This is the first report of PAD and HHD in a single family, suggesting that PAD and HHD lie on a spectrum of disease and are genetically linked. © 2016 British Association of Dermatologists.

    Robustness to environmental or genetic perturbation, like any other trait, is affected by evolutionary change. However, direct studies on the interplay of robustness and evolvability are limited and require experimental microevolutionary studies of developmental processes. One system in which such microevolutionary studies can be performed is vulva development in the nematode Pristionchus pacificus. Three vulval precursor cells respond to redundant cell–cell interactions, including signals from the gonad and the epidermal cell P8.p. Interestingly, P. pacificus P8.p is involved in cell fate specification of the future vulva cells by lateral inhibition but is incompetent to respond to the inductive signal from the gonad itself. These functional properties of P8.p are unknown from other nematodes, such as Caenorhabditis elegans. We began an experimental and genetic analysis of the microevolution of P8.p function. We show that vulva misspecification events differ between Pristionchus strains and species. Similarly, lateral inhibition and developmental competence of P8.p evolved within the genus Pristionchus and between natural isolates of P. pacificus. Surprisingly, in some recombinant inbred lines of two distinct P. pacificus isolates, P8.p gained competence to form vulva tissue, a trait that was never observed in P. pacificus isolates. Our results suggest differences in developmental stability between natural isolates, and we hypothesize that the remarkable evolvability of redundant cell–cell interactions allows for adaptive evolution of robustness to developmental noise.

To describe the diagnosis and treatment of a 16-year-old girl with Crohn disease of the vulva, without onset of intestinal symptoms. Crohn disease was diagnosed by histopathology. The patient was treated with corticosteroids and followed for 1 year. After the final diagnosis, cutaneous lesions responded rapidly to corticosteroid treatment, which was gradually stopped after 6 months. The disease was well controlled at the 1-year follow-up. Crohn disease of the vulva can develop alone without the onset of intestinal symptoms. Diagnosis relies on special pathologic findings.

    Juvenile-Takayasu arteritis (j-TA) is a difficult diagnosis and some patients develop uncommon manifestations and associated diseases that may contribute to the delayed diagnosis. Our aim was to identify the misdiagnoses, the associated diseases and the atypical manifestations observed in a j-TA Brazilian multicentre study. 71 children and adolescents who met the classification criteria for j-TA were included. The misdiagnoses, the associated diseases and the atypical manifestations were evaluated. 19 (26.8%) patients had misdiagnoses. The most common of them was aortic coarctation in six (8.4%) patients, followed by rheumatic fever in five (7.0%) and one patient presented with both former diagnoses. Limb pain (two patients), spondyloarthropathy, juvenile idiopathic arthritis (JIA), spinal arteriovenous malformation, polyarteritis nodosa (PAN) and fever of unknown origin (FUO) were other misdiagnoses. Patients who had misdiagnoses previously to j-TA diagnosis presented a trend to have a longer diagnosis delay. 11 (15.5%) patients had 14 TA-associated diseases, such as pulmonary tuberculosis (5 patients), rheumatic fever (2 patients), spondyloarthropathy, polyarticular JIA, Crohn's disease, Prader-Willi disease, diabetes mellitus, Moyamoya and primary immunodeficiency. 7 (9.9%) patients presented 10 atypical manifestations, such as pyoderma gangrenosum, erythema nodosum, myositis, chorea, enthesitis, episcleritis, uveitis, hepatomegaly, splenomegaly and necrosis of extremities. Our study emphasizes the main misdiagnoses, associated diseases and atypical manifestations that occur in patients with j-TA and warns of the features that may alert paediatricians to this diagnosis, such as constitutional symptoms and elevated inflammatory markers.

    Primary malignant lymphomas affecting the female reproductive system are unusual, accounting for about 30% of all lymphomas. The majority of them are represented by non-Hodgkin lymphomas (over 90%), as their location most commonly involved the ovarian (49%), followed by the uterus (29%), fallopian tubes (11%), vagina (7%), and only in 4% of the cases, the primary lymphomas affecting the vulva. Although rare, lymphomas of the vulva are characterized by high proliferative potential, aggressive clinical course and poor prognosis and may lead to rapid vulvar and perineal destruction. Due to the rarity of their occurrence in the vulvo-vaginal area and their non-specific clinical manifestations, lymphomas with such location are often a diagnostic challenge and require a wide range of differential diagnoses. We present the epidemiological structure, the clinical and immunohistochemical markers characteristic of the most common lymphomas with vulvar localization, in order to emphasize their role in the differential diagnosis of vulvar tumor masses.

    Primary lacrimal canaliculitis (PLC) is a unique disorder which often gets misdiagnosed by the general as well as speciality-trained ophthalmologists. Elderly patients with history of chronic or recurrent epiphora with discharge, often get mislead towards chronic dacryocystitis. The aim of our report is to discuss the misleading diseases in our PLC patients and to revisit this hidden disease. The patients of PLC who were previously misdiagnosed were studied. The clinical history, presenting clinical features, misdiagnosis, and final management of the patients is described. There were 5 misdiagnosed female patients. A history of chronic redness, watering, discharge, and medial canthal region edema lead to the misdiagnosis of chronic dacryocystitis in 3 (60%) and medial marginal chalazion in 2 (40%) cases. Slit-lamp examination revealed localized hyperemia (n = 5), classical pouting of lacrimal punctum (n = 3), and expressible purulent discharge (n = 3). Two patients without punctum pouting had an explicit yellowish hue/discoloration of the canalicular region. Our patients had a mean 4 visits before an accurate diagnosis. Three-snip punctoplasty with canalicular curettage was performed in three while two were managed conservatively. At last follow-up, all patients were symptom-free with punctum and canalicular scarring in three, who underwent surgery. PLC is a frequently misdiagnosed clinical entity which delays the initiation of appropriate treatment. A succinct magnified examination of punctum and canalicular region can provide sufficient clues pivotal for accurate diagnosis.

    2000-11-01

    The Caenorhabditis elegans vulva develops from the progeny of three vulval precursor cells (VPCs) induced to divide and differentiate by a signal from the somatic gonad. Evolutionarily conserved Ras and Notch extracellular signaling pathways are known to function during this process. To identify novel loci acting in vulval development, we carried out a genetic screen for mutants having a protruding-vulva (Pvl) mutant phenotype. Here we report the initial genetic characterization of several novel loci: bar-1, pvl-4, pvl-5, and pvl-6. In addition, on the basis of their Pvl phenotypes, we show that the previously identified genes lin-26, mom-3/mig-14, egl-18, and sem-4 also function during vulval development. Our characterization indicates that (1) pvl-4 and pvl-5 are required for generation/survival of the VPCs; (2) bar-1, mom-3/mig-14, egl-18, and sem-4 play a role in VPC fate specification; (3) lin-26 is required for proper VPC fate execution; and (4) pvl-6 acts during vulval morphogenesis. In addition, two of these genes, bar-1 and mom-3/mig-14, are known to function in processes regulated by Wnt signaling, suggesting that a Wnt signaling pathway is acting during vulval development.

    Proliferative myositis (PM) is a rare inflammatory disease. Most commonly, the lesion occurs in the extremities. Regarding its fast growth and bizarre shape of the cellular components this entity commonly misdiagnosed and the patients undergo improper therapeutic approaches. In other words, it is often misdiagnosed as sarcoma. The diagnosis can only be made by the microscopic examination, so biopsy is mandatory. Here the authors report a patient with PM who was initially misdiagnosed as pleomorphic sarcoma of the lower extremity and explain this rare entity. Proliferative myositis should be taken into account if a fast growing, intramuscular mass occurs in the extremities.

    2014-09-01

    The vulva search corresponds to the first step of mating in Caenorhabditis elegans wherein the male recognizes a potential mate through contact and commences a systematic, contact-based search of her surface for the vulva. During this 'dance' the male presses his tail genitalia firmly against the hermaphrodite surface and moves backward, modulating tail posture to effect changes in search trajectory. Upon sensing the vulva, the male pauses and the insemination phase of mating begins. External tail sensilla, the rays, induce and guide the male's search by registering hermaphrodite surface cues. C. elegans male mating behavior, like many other animate interactions (such as predator-prey interactions or intrasexual aggression), is performed at close quarters and requires that participants constantly adjust their movement with respect to one another on a moment-by-moment basis. The design features of the supporting circuitry explain simultaneously the robustness, speed and acuity of the male's behavior and its male-specific nature. Processing at all levels of the circuitry appears to be distributed. Cellular components exhibit both partial redundancy (thus conferring robustness in output) and subtle functional differences (predicted to confer acuity). Surprisingly, gender-shared cell types feature prominently in the circuitry. Male-specific components form sensory pathways that render downstream gender-shared circuits responsive to mate cues, while other male cells act to augment gender-shared cell activity. Overall, the attributes of the vulva search circuitry provide insight into principles guiding the design and operation of circuits supporting dynamic social behaviors expressed by more complex and less tractable animal species.

    2017-06-01

    Female genital cosmetic surgery is becoming more and more widespread both in the field of plastic and gynaecological surgery. The increased demand for vulvar surgery is spurred by the belief that the vulva is abnormal in appearance. What is normal in terms of labial anatomy? Labia minora enlargement or hypertrophy remains a clinical diagnosis which is poorly defined as it could be considered a variation of the normal anatomy. Enlarged labia minora can cause functional, aesthetic and psychosocial problems. In reality, given the wide variety of vulvar morphology among people, it is a very subjective issue to define the "normal" vulva. The spread of nudity in the general media plays a major role in creating an artificial image and standards with regard to the ideal form. Physicians should be aware that the patient's self-perception of the normal or ideal vulva is highly influenced by the arguably distorted image related to our socio-psychological environment, as presented to us by the general media and internet. As physicians, we have to educate our patients on the variation of vulvar anatomy and the potential risks of these surgeries.

Seven patients received radiation for vulvar cancer, three for distal vaginal cancer, and two for recurrent endometrial cancer. No patient healed spontaneously and the mean delay in surgical therapy was 8.5 months. The radionecrotic site was treated with local therapy, radical local excision (with or without colostomy), or exenteration. The operative defect was closed primarily in three patients and covered with local flaps or myocutaneous flaps in seven patients. The two patients with local care still have radionecroticmore » ulcers. One of three patients who were closed primarily continues to have an ulcer. All other patients have healed satisfactorily except one who died after two attempts to correct the problem.

    The occurrence of primary breast cancer of the vulva is extremely rare (24 cases described in the English-language literature). We report a case of a primary breast carcinoma of the vulva. An 82-year-old woman presented with a nodule of the left labia minor, which was excised. The histologic examination revealed the presence of adenocarcinoma of mammary origin, positive for common breast markers and for estrogen and progesterone receptors. The study for orthotopic breast carcinoma was negative, as well as the study for metastatic disease. The diagnosis of primary breast carcinoma was established. Our patient was then submitted to pelvic and inguinal radiotherapy as well as an aromatase inhibitor (letrozole), and she remained completely asymptomatic. Because of the rarity of this condition, guidelines for therapy are unavailable. The management suggested in the literature is that of primary orthotopic breast neoplasm of a similar stage.

    To investigate the long-term outcome of patients presenting with vulvar intraepithelial neoplasia (VIN) with superficially invasive carcinoma of the vulva (SICa). A retrospective study using information obtained from patient case notes. Twenty-six women found at presentation to have VIN in association with superficially invasive carcinoma were identified during a 15-year period. Pruritus vulvae was the most frequent presenting symptom in 18 patients (69%). Sixteen women (61.5%) had multiple symptoms. Features noted at vulvar examination were variable and none were pathognomonic of either VIN or of superficial invasion. All patients had VIN 3 in association with a superficially invasive carcinoma. Histological changes associated with human papillomavirus were found in 19 (73%) women. Half had a co-existent or previous abnormality of the lower genital tract. Local excision was the most frequent initial treatment (n = 9 [35%]). Mean follow up time was 65 months (range 12-174). Disease persisted after primary treatment in five women (19%). Both histological recurrence (of either VIN or SICa) or symptomatic recurrence occurred in 10 patients (38%). All patients who experienced recurrence did so within 36 months of treatment. Overall, 12 patients (46%) relapsed (histological or symptomatic recurrence); the mean time was 18 months. Fourteen patients (54%) were managed satisfactorily by their initial treatment. One patient died of recurrent cervical cancer. Three progressed to frankly invasive disease: two (aged 31 and 39 years) with carcinoma of the vulva and one aged 34 years with carcinoma of the perianal margin. All are alive and well after treatment. One patient had recurrence of superficially invasive carcinoma treated by local excision with no further problems. No episode of metastasis via lymphatic or vascular channels has been seen. Patients with superficially invasive carcinoma of the vulva may be safely treated by local excisional methods without recourse to

    Delirium can be conceptualized as an acute decline in cognitive function that typically lasts from hours to a few days. Prolonged delirium can also affect patients with multiple predisposing and/or precipitating factors. In clinical practice, prolonged delirium is often unrecognized, and can be misdiagnosed as other psychiatric disorders. We describe a case of a 59-year-old male presenting with behavioral and cognitive symptoms that was first misdiagnosed as a mood disorder in a general hospital setting. After prolonged delirium due to multiple factors was confirmed, the patient was treated accordingly with symptomatic management. He evolved with progressive improvement of his clinical status. Early diagnosis and management of prolonged delirium are important to improve patient prognosis and avoid iatrogenic measures.

    Red patches and plaques of the vulva may be manifestations of neoplasms, infections, or inflammatory skin diseases. These diseases can mimic one another clinically; features that generally allow the diseases to be identified on most cutaneous surfaces can be altered in the moist, occluded vulvar environment, making clinical diagnosis difficult. A detailed history and thorough physical examination can point to the likely diagnosis, but biopsy and culture may be needed for diagnosis especially in refractory disease. It is not uncommon for several of these processes to be present concomitantly or complicating other vulvar diseases. Copyright © 2017 Elsevier Inc. All rights reserved.

    Paraganglioma is a neuroendocrine neoplasm, which is extremely rare in the vulva and only one case has been reported. Here we present a case of vulvar paraganglioma in a 48-year-old woman and a literature review. The patient found a lump located in the genitals below the symphysis pubis 3 months before presentation when she complained that the lump was increasing in size. A 3.2 cm x 2.3 cm x 1.5 cm nodule was excised from subcutaneous soft tissue in the vulva. Microscopy showed a diversity of cell morphologies and structures in the rich vascular network of the tumor separated the chief cells into round cell nests (Zellballen pattern). Some areas of the tumor presented epithelioid and spindle-shaped cells with increased cell density and indistinct structural characteristics. Hyaline degeneration of collagen fibers or mucoid degeneration was found in tumor interstitium. Immunohistochemical staining showed diffused expression of synaptophysin in the chief cells, focal expression of S-100 protein in the sustentacular cells and high expression of CD34 in the vascular components. Based on morphological and immunohistochemical results, a rare paraganglioma of the vulva was diagnosed. PMID:24133606

    We report the case of a patient with carcinoma "en cuirasse" of the vulva. A female patient presented complaining of inguinal lymphadenopathy. Lymph node excision, immunohistochemistry analyses, and further exams showed the presence of cervical adenocarcinoma. The cancer was surgically removed and the patient was treated with radiotherapy and chemotherapy with a good initial response. Some months later she presented with intense edema of the lower limbs, hardening and thickening of the labia majora, and pelvic and genital ulceration. A cutaneous biopsy with subsequent immunohistochemical staining showed lymphatic dissemination of adenocarcinoma to the vulva. Carcinoma "en cuirasse" is a rare presentation of cutaneous metastasis in which the affected skin shows hardening and induration, acquiring a sclerodermoid appearance. This is, to the best of our knowledge, the first report in Brazil of carcinoma "en cuirasse" of the vulva associated with cervical adenocarcinoma.

    Vulvar Paget's disease is an extremely rare neoplasm that accounts for less than 1% of the vulvar malignancies. We present a case of a 75-year-old woman, who had an eczematoid lesion involving the labia majora and minora bilaterally, with infiltration to the clitoris. Enlarged non-fixed lymph nodes were palpable in the inguinal region bilaterally. A biopsy of the vulva showed Paget's disease. She underwent radical vulvectomy with bilateral inguinal lymph node dissection. The patient remained disease free at 6-month follow-up.

A symptom complex of pruritus and superficial dyspareunia was found in 98 of the 148 patients with vulvar infection (66%). Histologic examination revealed HPV-associated vulvar intraepithelial neoplasia (VIN) in 11 of 148 biopsies (7.4%). Follow-up of the patients with HPV infection with or without VIN showed a spontaneous regression rate of 56% but also demonstrated progression to VIN 3 in two patients and to invasive carcinoma of the vulva in one.

  3. Study of pruritus vulvae in geriatric age group in tertiary hospital

    Background: According to the World Health Organization criteria, geriatric population is people above 60 years of age. In this phase of life, a woman has already gone through menopause and its associated emotional, physical, and hormonal changes. These changes are due to gradual loss of estrogen that comes with menopause which results in dramatic changes in the appearance of vulva and vagina. With age, skin of vulva becomes thin, loses elasticity, and moisture so that the patient starts feeling burning and itchy sensation. The normal acidic pH changes to basic which alters the flora and makes the person prone to other bacterial infections. Apart from infections, there are many other dermatological and nondermatological causes of vulvar itching in this age group such as eczema, contact dermatitis, lichen planus (LP), lichen sclerosus atrophicans, lichen simplex chronicus (LSC), prolapse, incontinence, and carcinoma. The aim is to diagnose the causes of pruritus vulvae in the geriatric age group to decrease the misery of these patients. Methods: We selected 40 consecutive females of age group ranging from 60 to 75 years coming to skin OPD with the complaint of pruritus of vulvar region over a period of 1 year. Clinical examination, complete blood count, fasting blood sugar, wet mount, pap smear, and skin biopsy were done in every case. Results: Out of the forty patients who were included in this study, 17 (42.5%) were diagnosed as a case of LSC and 11 (27.5%) patients had atrophic vaginitis. Three (7.5%) patients presented with tinea. Three (7.5%) cases were clinically diagnosed as scabies. Another 2 (5%) cases were diagnosed as LP and Candida was seen in other 2 (5%) cases. 1 (2.5%) case was diagnosed as bacillary vaginosis and 1 (2.5%) patient was of lichen sclerosus. Conclusion: Pruritus vulvae of geriatric age group are of diverse etiology, therefore, treatment based on precise diagnosis is of prime importance. PMID:28442799

    To analyze our surgical management and the result of squamous cell carcinoma (SCC) of vulva. Retrospectively, we collected 38 cases of SCC; 17 cases of them were early SCC and 21 cases were locally advanced. The patients underwent primary surgery. The survival was estimated using Kaplan-Meier analysis and the log rank test. The mean age was 60.78 years. Total vulvectomy was performed in all patients. Superficial and deep incision of bilateral inguinal lymphadenectomy was performed by separates incisions for SCC infiltrating more than 1mm. The average tumor size was 53 mm (10 to 140mm). Morbidity was 42.1%. Lateral resection margin ≥8mm was obtained in 57.1%. Eighteen patients benefited from adjuvant radiotherapy. The follow-up median was 19.4 months (6 to 61.5 month) with 05 recurrences in 12 months. The survival using the Kaplan-Meyer analysis at 5 years, was 62.1% (71.2%N(-) vs 46.7%N(+); p = 0.13). We identified two groups for locally advanced vulva cancer. Primary surgery keeps its place. Neo adjuvant radio chemotherapy followed by surgery is the alternative treatment for locally extensive lesions.

    Inflammatory processes affecting the vulva may present a unique challenge due to location specific changes. Different factors are behind the intricacy in the presentation of vulvar dermatoses. First, the vulva is lined by different epithelia (hair-bearing keratinized epithelium, modified mucosa, and mucosa). Furthermore, among other factors, this organ is exposed to friction, occlusion, and trauma. Lastly, as there is a tendency to look for health care advice at an advanced stage of the disease, the lesion may be modified by secondary changes due to self-treatment. This article describes the clinical presentation and pathologic features of vulvar dermatoses with a lichenoid pattern and highlights practical points for their diagnoses.

    Ewing sarcomas/peripheral primitive neuroectodermal tumors (ES/pPNET) are extremely rare in the vulva. A review of the literature reveals only 14 previously reported possible cases. Here we reported a case of primary extraskeletal Ewing's sarcoma (EES) of the vulva in a 37-year-old woman. Characteristic histologic features of ES/pPNET were present in this case, including a monomorphic population of small round blue cells with cytoplasmic glycogen confirmed by periodic acid-Schiff, membrane staining with CD99 and nuclear staining with FLI-1. After surgery, the patient was found to have pulmonary metastasis and then received six cycles of polychemotherapy. She is still alive with stable disease after 1 year of follow up. Our findings underline the crucial role of immunohistochemical techniques in the differential diagnosis of small round cell tumors in these unusual locations. We also give a summary about the clinical and pathological features of the primary ES/pPNET in the vulva reported previously in the literature. © 2012 The Authors.

    To explore the related factors to influence the curative effect of focused ultrasound treatment for non neoplastic epithelial disorders of vulva. A total of 382 patients with non neoplastic epithelial disorders of vulva were included in this study and treated by focused ultrasound. During and after the treatment, the symptoms and physical signs of the subjects were observed, and the efficacy was evaluated. We analyzed the relation between pathologic type, age, course, area, or itch degree and curative effect. Symptoms of all patients were relieved, and appearance and color of the vulva became normal after the ultrasound treatment, with a total effective rate of 99.74%. The cure ratios of patients with different pathologic types, ages, courses, areas, and itch degrees were significantly different (χ(2)=9.58, P<0.01; χ(2)=22.385, P<0.01; χ(2)=32.260, P<0.01; χ(2)=57.99,P<0.01; χ(2)=42.13,P<0.01, respectively). Focused ultrasound treatment is safe and effective for the nonneoplastic epithelial disorders of the vulva and the efficacy is associated with the pathologic type, age, course, area, and itch degree.

    Thirty six patients with Paget's disease of the vulva were reviewed. The median age of the patients at diagnosis was 67 years (range: 45-91 years). One patient had a history of previous mammary adenocarcinoma. Screening for malignancy revealed two colonic tumours. Two patients with negative screening at presentation developed, 12 and 18 months respectively after vulvectomy, an ovarian carcinoma stage IIc and a cervical and urethral adenocarcinoma. All patients were treated by surgery based on extent of the disease. The operations performed included total vulvectomy (n = 11), partial vulvectomy (n = 14) and wide local excision (n = 4). Out of the 36 patients, 29 were available to follow-up. The median follow-up period was 74 months (range 2-204 months). Three patients died of metastatic disease due to vulval adenocarcinoma and breast carcinoma, or of liver metastases from an unknown adenocarcinoma. Eighteen of the 29 patients followed up remained free of disease. Five out of the 16 patients with positive margins recurred, as did 5 out of 9 patients with negative margins. Treatment of Paget's disease of the vulva is surgical. In order to prevent recurrence, some authors have proposed surgical excision extending beyond the visible clinical lesions with intraoperative frozen sections. The data we recorded show that free margins do not seem to correlate with recurrence, so that large excision beyond the clinical lesion is not useful.

    Recurrent vulvovaginal candidosis is a frequent disease with a serious impact on women's quality of life. Mostly, recurrences are caused by identical Candida strains suggesting C. albicans persistence in the female anogenital area. Objectives of the presented work were to identify the site of C. albicans persistence, to determine clinical symptoms and signs related to C. albicans positive vulvar cultures and to introduce a new therapeutic approach in women with RVVC. Women with an acute, culture-confirmed episode of RVVC at time of visit were included in this prospective case series. Swabs were obtained from both vagina and inter-labial sulcus. Women received a combined 20-day regimen of 100 mg oral fluconazole and ciclopiroxolamin cream topically. Follow-up visits were at 3, 6, 9 and 12 months. Of 139 women, 105 (76%) had at least one C. albicans positive culture from the external vulva. Vulvar positive cultures correlated with pruritus (OR 5.4; P < 0.001), vulvar edema (OR 3.8; P = 0.03) and fissures (OR 2.4; P = 0.03). Recurrence rates were 27%, 33% and 34% (at 6, 9, 12 months, respectively). The external vulva appears to represent a site of C. albicans persistence and source of endogenous re-infection in patients with RVVC. The combined treatment compared favorably with published fluconazole maintenance regimens. © 2011 Blackwell Verlag GmbH.

    Although the expression of the oestrogen receptor (ER) alpha isoform and androgen receptor (AR) has been examined in vulval lichen sclerosus (VLS), the distribution pattern of ERalpha, ERbeta and AR has not been described in chronic atrophic vaginitis nor correlated with markers of proliferation (Ki-67) in either of these diseased tissues. To measure the levels and distribution of ERalpha, ERbeta and AR immunoreactivity in relation to Ki-67 in normal and diseased vulva and vagina. The expression of ERalpha, ERbeta and AR in relation to the proliferation marker Ki-67 in VLS, squamous hyperplasia of the vulva and chronic atrophic vaginitis was determined by immunohistomorphometric analysis and compared with that in normal vulva and vagina. VLS showed similar ERalpha and ERbeta expression in the 'epidermal' and 'dermal' tissue layers to that of normal vulvae, whereas AR expression appeared to be absent in most cases. ERbeta and Ki-67 expression was correlated with ERalpha expression but only in the 'fibrovascular' layer of the vulva. ERalpha expression was absent from the 'fibromuscular' layer of diseased vulvae, while ERbeta expression was absent in normal tissues but was highly expressed in diseased vulvae. ERalpha expression was significantly correlated with AR expression in the fibrovascular layer of the vagina and inversely correlated with Ki-67 staining in the parabasal cells of the epidermis in patients with chronic atrophic vaginitis. These data suggest that ER expression and levels may be implicated in the aetiopathology of VLS and chronic atrophic vaginitis.

    Gene silencing through promoter hypermethylation is a growing concept in the development of human cancers. In this study, we examined the contribution of aberrant methylation of promoter regions in methylation-prone tumor suppressors to the pathogenesis of vulvar cancer. Thirteen cell lines from 12 patients with squamous cell carcinoma of the vulva were evaluated for aberrant methylation status and gene copy number alterations, concomitantly, using the methylation-specific multiplex ligation-dependent probe amplification assay. Of the 22 tumor suppressor genes examined, aberrant methylation was observed for 9 genes: tumor protein p73 (TP73), fragile histidine triad (FHIT), von Hippel-Lindau (VHL), adenomatosis polyposis coli (APC), estrogen receptor 1 (ESR1), cyclin-dependent kinase inhibitor 2B (CDKN2B), death-associated protein kinase 1 (DAPK1), glutathione S-transferase pi (GSTP1), and immunoglobin superfamily, member 4 (IGSF4). The most frequently methylated genes included TP73 in 9 of 13 cell lines, and IGSF4, DAPK1, and FHIT in 3 of 13 cell lines. Methylation-specific polymerase chain reaction was performed for TP73 and FHIT to confirm aberrant methylation by methylation-specific multiplex ligation-dependent probe amplification. In the context of gene copy number and methylation status, both copies of the TP73 gene were hypermethylated. Loss or decreased mRNA expression of TP73 and IGSF4 by reverse transcription polymerase chain reaction confirmed aberrant methylation. Frequent genetic alterations of loss and gain of gene copy number included gain of GSTP1 and multiple endocrine neoplasia type 1 (MEN1), and loss of malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) and IGSF4 in over 50% of the squamous cell carcinoma of the vulva cell lines. These findings underscore the contribution of both genetic and epigenetic events to the underlying pathogenesis of squamous cell carcinoma of the vulva.

    Proliferating trichilemmal tumor (PTT) is a rare but morphologically distinct tumor that usually arises on the scalp of elderly women. It is composed of multiple cysts consisting of squamous epithelium with trichilemmal keratinization without granular layer interposition. Vulvar proliferating trichilemmal cyst is very rare, with, to the best of our knowledge, only 3 cases previously reported in the literature. We describe a 39-year-old woman with recurrent PTT on the left labium majus of the vulva, which had been excised from the same side 5 years before. She had a palpable nodule, approximately 2 cm in size, which was firm, mobile, and nontender; without erythema and ulceration; and covered by normal skin on the vulva. There was no inguinal lymphadenopathy. The lesion was removed by wide surgical excision; because of the tissue elasticity, primary closure was possible. The pathology result was reported as proliferating trichilemmal carcinoma with tumor-free margins. Although local recurrence after wide excision is rare, we recommend complete excision for treatment of PTT and long-term follow-up because of the possibility of recurrence.

    Soft-tissue reconstruction of the vulva following resection of malignancies is challenging. The function of perineal organs should be preserved and the reconstructed area should maintain an acceptable cosmetic appearance. Reconstruction with local flaps is usually sufficient in the primary phase after a radical vulvectomy. Numerous flaps have been designed for vulvar reconstruction usually based on circulation from the internal pudendal artery branches. In this paper we introduce our modification of the gluteal fold V-Y advancement flap as a primary reconstruction after a radical vulvectomy. Twenty-two patients were operated with a radical vulvectomy because of vulvar malignancies. The operation was primary in eight and secondary in 14 patients. The reconstruction of the vulva was performed in the same operation for each patient. All flaps survived completely. Wound complications were registered in three patients. Late problems with urinary stream were corrected in two patients. A local recurrence of the malignancy was observed in six patients during the follow-up period. Gluteal fold flap is easy to perform, has a low rate of complications and gives good functional results. Even a large defect can be reconstructed reliably with this method. A gluteal fold V-Y advancement flap is sensate and our modification allows the flap to be transposed with lesser dissection as presented before.

    Congenital hernia of the cord, also known as umbilical cord hernia, is an often misdiagnosed and under-reported entity, easily confused with a small omphalocele. It is different from postnatally diagnosed umbilical hernias and is believed to arise from persistent physiological mid-gut herniation. Its incidence is estimated to be 1 in 5000. Unlike an omphalocele, it is considered benign and is not linked with chromosomal anomalies. It has been loosely associated with intestinal anomalies, suggesting the need for a complete fetal anatomical ultrasound evaluation. We present a case of a fetal umbilical cord hernia diagnosed in a 28-year-old woman at 21 weeks gestation. The antenatal and intrapartum courses were uncomplicated. It was misdiagnosed postnatally as a small omphalocele, causing unwarranted anxiety in the parents. Increased awareness and knowledge of such an entity among health professionals is important to prevent unwarranted anxiety from misdiagnosis, and inadvertent bowel injury during cord clamping at delivery.

    We aimed to investigate the prevalence and spectrum of unusual benign neoplasms and tumor-like lesions presenting as vulvar polyps and papules, to study their clinical, pathologic, hormonal, and developmental features and whether they have important associations with other pathologic lesions or clinical diseases. We conducted a retrospective review study of 115 vulvar specimens over 7 years. Common lesions, for example, fibroepithelial polyps, skin tags, papillomas, abscesses, viral warts and common cysts, were excluded. We found 21 cases (18%) with uncommon benign vulvar lesions. They included 7 epithelial cysts, 3 vascular lesions, 3 glandular neoplasms, 3 endometrioses, 1 caruncle, 1 pilonidal sinus, 1 prolapsed urethra, 1 seborrheic keratosis, and 1 granular cell tumor. The age range was between 1 and 64 years with a mean age of 33 years. Most (86%) were 2.5 cm or less. Many were asymptomatic incidental pathologic findings that can be missed clinically. Nine cases have important clinical associations or coexisting incidental pathologic lesions. Some lesions demonstrated hormone receptors. Some were clinically confused with fibroepithelial polyps, abscesses, warts, melanocytic lesions, and tumors. In conclusion, although the vulva is a small compartment, its developmental and histologic complexity can result in a variety of unusual and rare benign polypoid and papular lesions, some unique to the vulva, which might present diagnostic challenges to the clinicians and pathologists. In addition, many bear controversy regarding their histogenesis and origin of development in the vulva. Copyright © 2014 Elsevier Inc. All rights reserved.

    To investigate the short- and long-term efficacy and influential factors of focused ultrasound for the treatment of non-neoplastic epithelial disorders of the vulva (NNEDV). A retrospective observational study. A gynaecologic department in a single centre in China. Patients with NNEDV were included in this study: 85 patients were diagnosed with lichen simplex chronicus (LSC), 44 patients with vulva lichen sclerosus (VLS), and seven patients with lichen planus (LP). A total of 136 eligible patients with NNEDV were treated with focused ultrasound. After the treatment, based on changes in the degree of symptom severity and local skin signs (lesion size, skin colour and elasticity) before and after treatment, the treatment effectiveness for each patient was assessed. We further analysed the relations among pathologic type, age, course and curative rate. Statistical analysis was performed using the Chi-square (McNemar) test. Improvement in the symptoms and physical signs and the predictive factors. Symptom relief was observed in all patients. The appearance and colour of the vulva returned to normal after the ultrasound treatment. Complete remission (CR) occurred in 68 of 136 (50%) patients (41 patients with LSC and 12 patients with VLS). The response rate was 93.38% (127/136). Seven patients who had a poor response to the first session of treatment were treated again with ultrasound therapy and a good response was observed. No severe complications were observed. There was no significant difference in treatment results among the different pathological types (P > 0.05). However, the course of the disease and the age of the patients were related to the treatment results (P < 0.05). NNEDV can be treated with focused ultrasound effectively and safely. The course of the disease and the age of the patients may be predictive factors. Patients with non-neoplastic epithelial disorders of the vulva can be safely and effectively treated with focused ultrasound. No significant

    For preinvasive lesions of vulva, a common term VIN -  vulval intraepithelial neoplasia is used. VIN is a histological dia-gnosis based on abnormal squamous epithelial proliferation. There are two types of VIN apart from their association with human papillomavirus (HPV). Undifferentiated (usual) vulval intraepithelial neoplasia is commonly associated with carcinogenic genotypes of HVP, whereas differentiated vulval intraepithelial neoplasia is not associated with high-risk genotypes of HPV. The article presents an overview of VIN occurence and epidemiology, its classification system and dia-gnostics. In conclusion, VIN therapeutical possibilities are presented. It can be treated with surgical therapy (local excision, partial vulvectomy, vulvectomy, laser vaporization) or medical therapy (imiquimod).

    Carcinoma vulva is a rare disease accounting for 1.3% of all gynaecological malignancies. The present study is a 10-year retrospective review of our experience of the surgical options, morbidity, failure pattern, and survival for invasive carcinoma vulva. Retrospective analysis of case records of 39 patients who underwent surgery for invasive vulval cancer between 2004 and 2013 in the Department of Surgical Oncology at the Government Royapettah Hospital, Chennai. The median age was 55 years. Radical vulvectomy was the preferred surgery. 31 patients underwent lymphadenectomy. Seroma formation and groin skin necrosis were the most common postoperative complications. With a median follow-up of 32 months, 8 patients (20.5%) developed recurrence (systemic = 1, regional = 4, and local = 3). The estimated 5-year disease-free survival (DFS) was 65.4% and the overall survival (OS) was 85.1%. On univariate analysis, stage and lymph node involvement significantly affected OS. Nodal involvement with extracapsular spread (ECS) significantly affected both DFS and OS. The treatment of carcinoma vulva should be individualized with multidisciplinary cooperation. The paucity of data, especially from India, necessitates the need for more studies, preferably multicentric, keeping in mind the low prevalence.

    Clinical and histological data of 168 patients with squamous cell carcinoma of the vulva were analyzed with respect to survival. 151 patients underwent surgery, 12 patients were treated with primary radiation and in 5 patients no treatment was performed. Follow-up lasted from at least 2 up to 22 years' posttreatment. In univariate analysis, the following factors were highly significant: presurgery lymph node status, tumor infiltration beyond the vulva, tumor grading, histological inguinal lymph node status, pre- and postsurgery tumor stage, depth of invasion and tumor diameter. In the multivariate analysis (Cox regression), the most powerful factors were shown to be histological inguinal lymph node status, tumor diameter and tumor grading. The multivariate logistic regression analysis worked out as main prognostic factors for metastases of inguinal lymph nodes: presurgery inguinal lymph node status, tumor size, depth of invasion and tumor grading. Based on these results, tumor biology seems to be the decisive factor concerning recurrence and survival. Therefore, we suggest a more conservative treatment of vulvar carcinoma. Patients with confined carcinoma to the vulva, with a tumor diameter up to 3 cm and without clinical suspected lymph nodes, should be treated by wide excision/partial vulvectomy with ipsilateral lymphadenectomy.

    Juvenile foveal retinoschisis is one of the most common causes of bilateral macular degeneration in young boys. School age with accommodative esotropia may develop amblyopia due to late correction of hyperopia. Retinoschisis is hard to diagnose in patient with subtle macula change and hyperopic amblyopia. We report a case of bilateral foveal retinoschisis before and after treatment with topical dorzolamide, which was misdiagnosed as bilateral hyperopic amblyopia. Optical coherence tomography should be considered in diagnostic procedures of children with hyperopic amblyopia.

    Cellular angiofibroma is a benign and rare tumor. It usually arises in middle-aged women and involves the vulva. Complete local excision of the tumor is the best cure, and, usually, there is no recurrence after surgery. We describe a 20-year-old woman with a painless, growing vulvar mass who presented about 3 years ago. Her past medical history was negative for oral contraceptives, tobacco, and alcohol, and there were no similar lesions in her family history. A physical examination revealed two masses on the right and the left labia majora and similar lesions on the left axilla and both breasts. An uncomplicated simple resection of the vulvar masses was done in the operating room. There was no evidence of recurrence 12 months after surgery. Histopathologic examination revealed that the findings were consistent with the diagnosis of the cellular angiofibroma. Based on our knowledge, this patient is the youngest case of vulvar angiofibroma. The lesions were large and symmetrical (on both labia majora), although they differed in size. Extravulvar (breast and axilla) lesions were also noteworthy in this patient.

    Merkel cell carcinoma (MCC) is a rare malignant neoplasm, mostly affecting the skin (97% of cases). It is usually found in elderly people, in the sun-exposed areas of the skin. About 50-60% of MCC cases are located on the head and the neck, less often on the extremities and the torso, and extremely rarely in the genital area. Ultraviolet radiation may be the main factor responsible for the development of the tumors but viral etiology is also debated. Due to extremely rare incidence of MCC in the area of the vulva, proper management remains a challenging task. To present a case of an aggressive MCC of the vulva and a review of the literature. A previously healthy 72-year-old patient presented at the Oncology Center of the Maria Sklodowska-Curie Institute, Warsaw, in June 2010. Four months previously the patient noticed a painless lump in the vestibular region of the vagina. She received anti-inflammatory treatment at her local gynecological clinic, with no success. In February the patient underwent removal of the vulvar tumor Histopathological examination confirmed anaplastic carcinoma. Microscopic evaluation revealed the tumor diameter to be 15mm. Surgical margins were free of neoplastic infiltration. The patient did not receive adjuvant therapy due to the results from the histopathological protocol. The disease recurred after three months. Radical vulvectomy and bilateral inguinal femoral lymphadenectomy were performed in May 2010. Histopathological examination confirmed microcellular carcinoma with no metastases to the lymph nodes and complete resection of the tumor (RO). The disease recurred in the next two months: a 50-mm tumor was found in the right inguinal lymph nodes. The decision to verify all histopathological material obtained during all procedures performed so far was made. Immunohistochemical evaluation confirmed MCC. Adjuvant radiotherapy was recommended. The area of the vulva, pelvic and inguinal lymph nodes were irradiated. One month after therapy

    Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia characterized by hypoplastic clavicles, late closure of the fontanels, dental problems and other skeletal features. CCD is caused by mutations, deletions or duplications in runt-related transcription factor 2 (RUNX2), which encodes for a protein essential for osteoblast differentiation and chondrocyte maturation. We describe three familial cases of CCD, misdiagnosed as rickets over three generations. No mutations were detected on standard DNA sequencing of RUNX2, but a novel deletion was identified on quantitative polymerase chain reaction (qPCR) and multiple ligation-dependent probe amplification (MLPA). The present cases indicate that CCD could be misdiagnosed as rickets, leading to inappropriate treatment, and confirm that mutations in RUNX2 are not able to be identified on standard DNA sequencing in all CCD patients, but can be identified on qPCR and MLPA. © 2015 Japan Pediatric Society.

    Many women use panty liners between menstrual periods. The aim of this study was to investigate whether the use of such products might influence the vulva skin. Twelve healthy women were studied on four occasions with three different product constructions and on one occasion without products. Temperature, surface wetness and surface pH were measured on vulva skin. Mean skin temperature when the women were wearing a conventional panty liner (with a non-breathable back sheet) was 35.9 degrees C, compared to 34.4 degrees C when wearing no panty liner at all (p < 0.01) and 34.5 degrees C when using a panty liner with a breathable (i.e. vapour permeable) back sheet (p < 0.01). Skin humidity was significantly higher when the conventional panty liner was used compared to no panty liner or to the breathable panty liner (both cases p < 0.01). The mean pH value at the exterior aspect of the labium majus was 5.8 with the conventional panty liner, 5.2 with no panty liner and 5.3 with the breathable panty liner (p < 0.001 and p < 0.01, respectively). The results indicate that the conventional panty liner changes the vulva skin microclimate, but that the breathable panty liner to a substantial degree keeps the microclimate at an undisturbed level. The actual effect of these differences on microbiological flora will be addressed in a subsequent study.

    This study aimed to describe 2 cases of vulvar psoriasis and vitiligo resulting in a striking clinical appearance. Case 1 was of a 41-year-old woman concerned about a dark pigmentation around the introitus. Case 2 was of an 80-year-old woman with vulvar itch and red, white, and brown areas. The vulva in each case showed a tricolored appearance of well-demarcated red, white, and brown colors. Biopsies showed psoriasis superimposed on vitiligo in the red, vitiligo in the white, and normal skin in the brown areas. When psoriasis and vitiligo are colocalized, the redness of the psoriasis may mask the vitiligo resulting in a striking red, white, and brown tricolored appearance.

    To study the clinicopathologic features of a rare disease of pagetoid urothelial intraepithelial neoplasia (PUIN) in the vulva. We reviewed a case of PUIN in a Chinese woman with a long history of bladder urothelial carcinoma. The patient presented with vulvar pruritus for more than 1 month. Gynecologic examination showed a red, thickened, eczematoid lesion in the bilateral labia minora and a palpable 4-cm mass between the middle part of the vagina and the urethral meatus. Microscopically, the neoplastic cells with clear or pale eosinophilic cytoplasm were distributed throughout the squamous epithelium, with a predilection for the middle and basal portion in the vulva. Acantholysis-related papillary formation and pagetoid spread pattern to the normal squamous epithelium were also present. Invasive carcinoma was found underneath the unremarkable squamous epithelium in the vaginal biopsy. Immunohistochemistry demonstrated that these cells were negative for mucin stain, carcinoembryonic antigen, and 34βE12 and were strongly positive for cytokeratins 5/6, 7, 18, 19, and 20. This rare entity of PUIN was associated with metastatic urothelial carcinoma and should be discriminated from vulvar Paget disease and pagetoid squamous cell carcinoma in situ.

    Vulva and Vaginal cancers are rare among all gynecological cancers worldwide, including Thailand, and typically affect women in later life. Persistent high risk human papillomavirus (HR-HPV) infection is one of several important causes of cancer development. In this study, we focused on HPV investigation and specific type distribution from Thai women with abnormality lesions and cancers of the vulva and Vaginal. A total of ninety paraffin-embedded samples of vulva and Vaginal abnormalities and cancer cells with histologically confirmed were collected from Thai women, who were diagnosed in 2003-2012 at the National Cancer Institute, Thailand. HPV DNA was detected and genotyped using polymerase chain reaction and enzyme immunoassay with GP5+/ bio 6+ consensus specific primers and digoxigenin-labeled specific oligoprobes, respectively. The human β-globin gene was used as an internal control. Overall results represented that HPV frequency was 16/34 (47.1%) and 8/20 (40.0%) samples of vulva with cancer and abnormal cytology lesions, respectively, while, 3/5 (60%) and 16/33 (51.61%) samples of Vaginal cancer and abnormal cytology lesions, respectively, were HPV DNA positive. Single HPV type and multiple HPV type infection could be observed in both type of cancers and abnormal lesion samples in the different histological categorizes. HPV16 was the most frequent type in all cancers and abnormal cytology lesions, whereas HPV 18 was less frequent and could be detected as co-infection with other high risk HPV types. In addition, low risk types such as HPV 6, 11 and 70 could be detected in Vulva cancer and abnormal cytology lesion samples, whereas, all Vaginal cancer samples exhibited only high risk HPV types; HPV 16 and 31. In conclusion, from our results in this study we suggest that women with persistent high risk HPV type infection are at risk of developing vulva and Vaginal cancers and HPV 16 was observed at the highest frequent both of these, similar to the cervical

    Dermatofibrosarcoma Protuberans (DFSP) of the vulva is rare and oncologic surgery with free margins may lead to severe functional damage, requiring multidisciplinary approach regarding resection, margin assessment and reconstruction.Case Report: Two cases of DFSP in vulva were treated in a single institution. A 28-year-old patient with an incisional biopsy in the vulvar region revealing DFSP underwent a partial vulvectomy with clitoris preservation. Pathological studies revealed free margins and reconstructive surgery was performed. This patient is disease free in a 40 months follow up. The other, a 57-year-old patient was also referred after an incomplete resection of a DFSP in the vulvar region. A 1-cm margim resection followed by Complete Circumferential and Peripheral Deep Margin Assessment (CCPDMA) was performed. Although the upper lateral margin was positive, it was possible to perform another wide local excision with preservation of the clitoris and primary closure. DFSP of the vulva requires an accurate evaluation of margins, resections following oncological principles and reconstruction. Although being a very challenging lesion that usually implies difficult surgical management, if treated in a multidisciplinary environment, with surgical oncologists, experienced dermatopathologists and reconstructive surgeons can achieve good results. Even in difficult cases that presents with large lesions and compromising challenging areas, a complete oncologic resection can be performed minimizing functional damage for the patient.

    Accessory breast tissue is a very rare finding in the general population with an incidence of one to two percent. An even rarer occurrence is accessory mammary-like tissue which developed breast carcinoma. The authors present a case of aggressive and metastatic carcinoma of vulvar originating from mammary-like tissue. A 73-year-old Caucasian female presented with a lesion in her left vulva. The lesion was ulcerated and fragile. A dermatologist had evaluated the lesion and took a punch biopsy. Result was vulvar carcinoma. She was admitted to the gynecologic oncology clinic then after and was operated. After a radical vulvectomy and bilateral inguinal lymphadenectomy she received adjuvant radiotherapy because of lymph node metastasis. One year after the finish of radiotherapy patient was found to have lung and femur metastasis. She began to receive systemic chemotherapy for metastasis. Primary mammary-like adenocarcinoma of the vulva is exceedingly rare. There is no consensus about the diagnosis, treatment, and follow up of these patients in literature. However, given that histological data confirms these cancers are behaving like breast cancers instead of known patterns of vulva cancer, the best treatment practices for breast cancer may be applied to treat these vulvar carcinoma patients.

    The female vulva is an intricate structure comprising several components. Each structure has been described separately, but the interplay among them and physiologic significance remain controversial. The structures extend inferiorly from the pubic arch and include the mons pubis, labia majora, labia minora, vestibule, and clitoris. The clitoris is widely accepted as the most critical anatomic structure to female sexual arousal and orgasm. The female sexual response cycle is also very complex, requiring emotional and mental stimulation in addition to end organ stimulation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Sixteen of 46 patients (35%) with Grade 3 vulvar intraepithelial neoplasia (VIN 3) were found to have an additional site of lower genital tract squamous cell neoplasia, primarily in the cervix. The frequency of multicentricity decreased significantly with age. In addition, patients with multicentric disease (involving the vagina and/or cervix in addition to the vulva) had a significantly higher frequency of multifocal disease involving the vulva (involving more than one location on the vulva) and of recurrence than patients without multicentric disease. Human papillomavirus (HPV) DNA was detected by in situ hybridization in 81% of the women with multicentric squamous cell neoplasia. No significant difference was noticed between patients with multicentric and unicentric squamous cell neoplasia in the detection rate of papillomavirus antigen, HPV DNA, the various HPV types, herpes simplex virus Type 2 (HSV2)-related antigen, type-specific antibodies to HSV, and dual HPV and HSV2 infections. These findings suggest that HPV and HSV2, although strongly associated with VIN 3, do not influence the development pattern of squamous cell neoplasia, and that all patients with VIN 3, especially if they are younger than 50 years of age, should be evaluated periodically for additional centers of lower genital tract squamous cell neoplasia.

    Most diversity in animals and plants results from the modification of already existing structures. Many organ systems, for example, are permanently modified during evolution to create developmental and morphological diversity, but little is known about the evolution of the underlying developmental mechanisms. The theory of developmental systems drift proposes that the development of conserved morphological structures can involve large-scale modifications in their regulatory mechanisms. We test this hypothesis by comparing vulva induction in two genetically tractable nematodes, Caenorhabditis elegans and Pristionchus pacificus. Previous work indicated that the vulva is induced by epidermal growth factor (EGF)/RAS and WNT signaling in Caenorhabditis and Pristionchus, respectively. Here, we show that the evolution of vulva induction involves major molecular alterations and that this shift of signaling pathways involves a novel wiring of WNT signaling and the acquisition of novel domains in otherwise conserved receptors in Pristionchus vulva induction. First, Ppa-LIN-17/Frizzled acts as an antagonist of WNT signaling and suppresses the ligand Ppa-EGL-20 by ligand sequestration. Second, Ppa-LIN-18/Ryk transmits WNT signaling and requires inhibitory SH3 domain binding motifs, unknown from Cel-LIN-18/Ryk. Third, Ppa-LIN-18/Ryk signaling involves Axin and β-catenin and Ppa-axl-1/Axin is epistatic to Ppa-lin-18/Ryk. These results confirm developmental system drift as an important theory for the evolution of organ systems and they highlight the significance of protein modularity in signal transduction and the dynamics of signaling networks.

    Malignant tumors arising from the vulva account for only 0.6 % of all cancers in female patients. The predominant histologic type, representing about 90 % of these malignancies, is squamous cell carcinoma. Eccrine porocarcinoma is a rare malignant tumor arising from sweat glands. The incidence of eccrine porocarcinoma is estimated at 0.005-0.01 % of all cutaneous tumors. To the best of our knowledge, only seven previous cases of vulvar eccrine porocarcinoma have been reported in the English-language literature. We present the case of a patient with eccrine porocarcinoma of the vulva, and we summarize the clinical features of this disease using seven previously reported cases. A 54-year-old Japanese woman visited a local hospital complaining of fever and left vulvar pain for 2 months. An initial examination revealed a 1 × 1 cm, firm, ulcerative mass in the inner aspect of the left labium minorum. With a preoperative diagnosis of vulvar squamous cell carcinoma, we performed a radical local excision followed by bilateral inguinal lymphadenectomy. Histological examination showed eccrine porocarcinoma, stage IB (T1bN0M0). Radiation therapy with weekly cisplatin administration was then given as adjuvant therapy. One month after treatment was completed, computed tomography revealed multiple metastases in the bilateral lungs and in the sacral bone. The patient received three courses of chemotherapy (paclitaxel and carboplatin) and underwent palliative radiation therapy to the sacrum. She died of her disease 12 months after surgery. We report the case of a patient with eccrine porocarcinoma of the vulva and summarize the clinical features and the treatment options of eccrine porocarcinoma from a few retrospective case reports. Although eccrine porocarcinoma is a rare disease, clinicians and pathologists should be aware of its clinical and histological features and its biological behavior.

    When a healthy woman expresses concerns about her vulva, the doctor's response should be informed by clinical knowledge. For many doctors, accumulation of such knowledge would have begun with undergraduate teaching and medical textbooks. The aim of this study is to examine the information on female genital morphology in medical textbooks. A total of 59 gynaecology and anatomy textbooks were searched for information on the dimensions of vulval constitutent parts. No textbook gave measurements for all vulval structures. Vaginal length was reported in 21/59 textbooks, clitoral size in 15/59 and labia minora in 1/59. Where measurements appear, they suggest narrower ranges than recent reports. Information of vulval morphology is scanty and inaccurate in medical textbooks. The general lack of professional resources means that doctors may consciously or non-consciously rely upon personal experiences and popular culture to form their opinions, as do their patients.

Here, we show that the evolution of vulva induction involves major molecular alterations and that this shift of signaling pathways involves a novel wiring of WNT signaling and the acquisition of novel domains in otherwise conserved receptors in Pristionchus vulva induction. First, Ppa-LIN-17/Frizzled acts as an antagonist of WNT signaling and suppresses the ligand Ppa-EGL-20 by ligand sequestration. Second, Ppa-LIN-18/Ryk transmits WNT signaling and requires inhibitory SH3 domain binding motifs, unknown from Cel-LIN-18/Ryk. Third, Ppa-LIN-18/Ryk signaling involves Axin and β-catenin and Ppa-axl-1/Axin is epistatic to Ppa-lin-18/Ryk. These results confirm developmental system drift as an important theory for the evolution of organ systems and they highlight the significance of protein modularity in signal transduction and the dynamics of signaling networks.

    We describe an unusual case of diffuse large B-cell lymphoma involving the vulva detected and staged by F-FDG PET/CT. An 83-year-old female patient with history of endometrial carcinoma underwent F-FDG PET/CT for follow-up. PET/CT detected an area of increased F-FDG uptake corresponding to a vulvar nodule; moderate and diffuse F-FDG uptake in the bone marrow was also evident. Based on these PET/CT findings, the patient underwent biopsy of the vulvar nodule. Histology demonstrated the presence of a diffuse large B-cell lymphoma of the vulva. Bone marrow biopsy was positive for lymphoid infiltration.

    Extramammary Paget disease of the vulva (EPDV) is a rare occurrence with an indolent and relapsing course. Progression to invasion occurs in 4% to 19% of cases. The aim of this study is to report clinical-pathological features and outcomes of patients treated for invasive EPDV. Data of consecutive patients treated between 2000 and 2017 for invasive EPDV were reviewed. Among 79 patients with EPDV, 10 (12.7%) presented a microinvasive or invasive form at first diagnosis or during follow-up. All of them underwent upfront radical surgery; 7 (70%) received subsequent radiotherapy, chemotherapy, or both. The mortality rate was 40%. The recurrence rate after treatment for invasive forms was 60%, with a mean time to first recurrence of 20 (range, 5-36) months. Our study confirms that invasive EPDV remains a rare gynecological neoplasm with a poor prognosis. Multicentre trials or well-organized prospective data collection could improve the knowledge about the management of invasive EPDV.

  4. Invisibility: the lived experience of women with cancer of the vulva.

    This study describes an exploration of the lived experience of 13 British women with cancer of the vulva who underwent surgical treatment. A review of the literature highlighted a paucity of knowledge as many studies were conducted during the 1980s and 1990s and investigated sexual functioning only. An interpretive phenomenological approach based on the work of Heidegger and van Manen was used to frame the study by posing the question, "What must it be like to be diagnosed with, and have surgery for a cancer of the vulva?" The women, younger than 50 years, were identified by purposive sampling and interviewed between 6 months and 5 years after surgery. The data were analyzed using framework analysis. The women's lived experience is described in its entirety by the concept of invisibility, characterized as something "no one can see," "heard of," and "talks about." The impact of this invisibility is discussed as the "invisibility of understanding" and "invisibility of support." Although many women may expect to be cured of their vulval cancer, the invisible nature of the condition and the resulting lack of understanding and support may continue for a considerable period, as every aspect of their everyday life and in their relationships may be affected. The challenge now is to raise awareness of this condition and provide greater informational and emotional support for these women.

    Histology sections from 61 cases of squamous cell carcinoma (SCC) of the vulva presenting after 1988 were reviewed for evidence of associated epithelial abnormality. Of the 50 patients with epithelium adjacent to the tumour, 24 had histological evidence of lichen sclerosus (LS), 20 of severe vulvar intraepithelial neoplasia (VIN 3), 22 of human papilloma virus (HPV) infection and three of lichen planus (LP). The clinical records and the original histology report were also subsequently reviewed and with the exception of VIN 3, these disorders were poorly reported by both clinicians and pathologists. Lichen sclerosus was diagnosed clinically in only two of the 36 hospital records available for inspection. Old terminology was used to describe some patients with epithelial disease (erythroleucoplakia in one patient with LS, leucoplakia in two patients with LS and one with LP). This study demonstrates the need to adopt standard nomenclature and increase the awareness of epithelial disease associated with SCC of the vulva among clinicians and pathologists.

    Melioidosis is endemic in Southeast Asia and Northern Australia. Sporadic cases have been reported from many parts of the world where it has an epidemic potential with high-rate fatality cases. In non-endemic areas, melioidosis may be misdiagnosed with common diseases and this may prove fatal. Sporadic cases of melioidosis are mistaken for tuberculosis in India. We report a case of splenic abscess due to chronic melioidosis who was earlier misdiagnosed as tuberculosis and underwent anti-tuberculosis therapy. Following treatment of melioidosis his symptoms subsided. This case is reported because of the rarity of the disease and to highlight the importance of looking for melioidosis in patients with splenic abscess even in non-endemic areas. PMID:24714690

    The Caenorhabditis elegans vulva is an elegant model for dissecting a gene regulatory network (GRN) that directs postembryonic organogenesis. The mature vulva comprises seven cell types (vulA, vulB1, vulB2, vulC, vulD, vulE, and vulF), each with its own unique pattern of spatial and temporal gene expression. The mechanisms that specify these cell types in a precise spatial pattern are not well understood. Using reverse genetic screens, we identified novel components of the vulval GRN, including nhr-113 in vulA. Several transcription factors (lin-11, lin-29, cog-1, egl-38, and nhr-67) interact with each other and act in concert to regulate target gene expression in the diverse vulval cell types. For example, egl-38 (Pax2/5/8) stabilizes the vulF fate by positively regulating vulF characteristics and by inhibiting characteristics associated with the neighboring vulE cells. nhr-67 and egl-38 regulate cog-1, helping restrict its expression to vulE. Computational approaches have been successfully used to identify functional cis-regulatory motifs in the zmp-1 (zinc metalloproteinase) promoter. These results provide an overview of the regulatory network architecture for each vulval cell type. PMID:19104047

    A 16-year-old girl presented with a 9-year history of vesicles on the vulva. She had initially taken a wait-and-see approach, but required treatment because of bleeding. Histological examination of a biopsied vesicle revealed dilated lymph channels in the upper dermis, suggesting lymphangioma circumscriptum (LC). The challenge for this pathology has been to find a conservative treatment with low morbidity and better results than those reported for surgical excision, which has been the mainstay of therapy. In this case, LC of the vulva was successfully treated using a 10,600-nm CO2 laser and long-pulsed Nd:YAG laser. Use of the 10,600-nm CO2 laser and long-pulsed Nd:YAG laser appeared effective for treating LC.

    Stiff person syndrome (SPS) is a rare neurological disease resulting in stiffness and spasm of muscles. It initially affects the axial muscles and then spread to limb muscles. Emotional stress exacerbated the symptoms and signs of the disease. The pathophysiology of the disease is caused by the decreased level of the glutamic acid decarboxylase (GAD) activity due to an autoantibody against GAD that decreases the level of gamma-aminobutyric acid (GABA). In this paper, we present a case of atypical presentation of SPS with lower limb stiffness misdiagnosed as conversion disorder. We report a patient with atypical presentation of SPS with lower limb stiffness and gait disorder misdiagnosed as conversion disorder for a year. Her antithyroid peroxidase antibody (anti-TPO Ab) level was 75 IU (normal value: 0-34 IU). Intravenous immunoglobulin (IVIG) was administered (2gr/kg, 5 days) for the patient that showed significant improvement in the follow-up visit. It is essential that in any patient with bizarre gait disorder and suspicious to conversion disorder due to the reversibility of symptoms, SPS and other movement disorder should be considered.

    It is rare to see large vulvar growths that are not trauma related in young women. The largest vulvar mass recorded dates back to 1851. Fibroma of the vulva is not common but, if not seen early and removed, can be emotionally draining for the patient. A large vulvar mass was found in an 18-year-old woman and was expeditiously excised. The patient was emotionally withdrawn and would not participate in any school or social activities. She would carry moist paper towels with her to prevent maceration of the lower abdomen and lesion wall. An extraordinary physical finding can embarrass and alter a patient's demeanor and should be addressed without delay. The emotional condition of our patient prior to surgery consisted of depression and emotional stress due to the large vulvar mass. Following surgery the patient was comfortable, and her demeanor is now excellent.

    Vulvar cancer is a rare malignancy; most tumors are squamous cell type while adenocarcinomas are rare. Primary adenocarcinomas of the vulva predominantly include extramammary Paget's disease and sweat gland carcinomas. Greene first described a rare form of adenocarcinoma in 1936, which was called adenocarcinoma of mammary-like glands of the vulva because of its morphologic and immunohistochemical resemblance to breast adenocarcinomas. In the management of this entity, varying combinations of surgery, radiation therapy, systemic chemotherapy and/or hormonal therapy may be used, as in patients with orthotopic breast carcinoma. However, hormonal therapy leads the way in patients with positive hormonal receptors, where other therapies cannot be used due to comorbidities or advanced age. We present the first reported case of an elderly patient with metastatic vulvar adenocarcinoma arising from mammary-like glands, successfully treated with a combination of surgery and hormonal therapy. © 2012 The Authors.

    A 66-year-old patient was treated with external radiation therapy for an advanced carcinoma of the vulva. Seven years later, a lymphangiosarcoma developed in her edematous lower extremity. Lymphangiosarcomas have been reported to occur in postmastectomy patients; however, this is only the third case in a patient with a gynecologic primary malignancy. In anticipation of possible increased use of radiation therapy in vulvar carcinoma, gynecologists should be aware of this rare, highly aggressive neoplasm.

    Vulvar cancer accounts for less than 1% of malignancies in women. Verrucous carcinoma of the vulva is a rare histological variation, comprising less than 1% of vulvar cancer cases. Although it is characterized as being locally invasive, the condition is not associated with metastatic spreading. Lesions present in the form of a verrucous, ulcerated, and bleeding tumor that can reach large dimensions. This type of tumor can be mistaken for condylomata, both macroscopically and microscopically. We report the case of an 81-year-old patient with a large vulvar tumor presented for eight years, initially considered as a Buschke-Löwenstein tumor. The patient underwent radical vulvectomy with a V-Y advancement flap technique. This type of tumor should be considered by clinicians dealing with condylomatous ulcerative lesions that do not respond to the usual treatment.

    Chronic anal fissure is a linear ulcer in the anal canal that has not cicatrized for more than 8-12 weeks of treatment. Most anal fissures are idiopathic and are located in the posterior midline. Squamous cell carcinoma of the anus commonly presents as bleeding and anal pain. It may also present as a mass, nonhealing ulcer, itching, discharge, fecal incontinence and fistulae. Not uncommonly, small and early cancers are misdiagnosed as benign anorectal disorders like anal fissures or hemorrhoids. The clinical suspicion of squamous cell carcinoma of the anus is of paramount importance in patients with nonhealing anal fissures, fissures in atypical positions or with indurated or ulcerated anal tags and in patients with risk factors for the development of anal squamous intraepithelial lesions that are precursors of invasive anal squamous cell carcinoma. The authors present 3 cases of squamous cell carcinoma of the anus initially misdiagnosed as benign chronic anal fissure.

    A new approach to improving the diagnostic value of optical methods is suggested, which is based on a complementary investigation of different optical parameters of biotissues. The aim of this paper is comparative study of the feasibility of two optical methods - fluorescence spectroscopy and optical coherence tomography - for visualization of borders of neoplastic processes in the uterine cervix and vulva. Fluorescence spectroscopy is based on the detection of biochemical and optical coherence tomography on backscattering properties in norm and pathological changes of tissues. By means of these optical methods changes in biochemical and morphological properties of tissues were investigated. A parallel analysis of these two optical methods and histology from the center of tumors and their optical borders was made. Thirteen female patients with neoplastic changes in uterine cervix and vulva were enrolled in this study. The borders of the tumor determined by optical methods (fluorescence spectroscopy and optical coherence tomography) are coinciding with the biopsy proved ones. In addition, OCT and fluorescence borders of tumor in the uterine cervix and vulva exceeds colposcopically detectable borders, the averaging difference 2 mm. In future optical methods would considerably enhance diagnostic accuracy of conventional methods used in oncogynecology.

    Sexual health is vital to overall well-being. Orgasm is a normal psycho-physiological function of human beings and every woman has the right to feel sexual pleasure. The anatomy of the vulva and of the female erectile organs (trigger of orgasm) is described in human anatomy textbooks. Female sexual physiology was first described in Dickinson's textbook in 1949 and subsequently by Masters and Johnson in 1966. During women's sexual response, changes occur in the congestive structures that are essential to the understanding of women's sexual response and specifically of their orgasm. Female and male external genital organs arise from the same embryologic structures, i.e. phallus, urogenital folds, urogenital sinus and labioscrotal swellings. The vulva is formed by the labia majora and vestibule, with its erectile apparatus: clitoris (glans, body, crura), labia minora, vestibular bulbs and corpus spongiosum. Grafenberg, in 1950, discovered no "G-spot" and did not report an orgasm of the intraurethral glands. The hypothetical area named "G-spot" should not be defined with Grafenberg's name. The female orgasm should be a normal phase of the sexual response cycle, which is possible to achieve by all healthy women with effective sexual stimulation. Knowledge of the embryology, anatomy and physiology of the female erectile organs are important in the field of women's sexual health. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Lichenoid keratosis (LK), also known as benign lichenoid keratosis or lichen planus-like keratosis, is a solitary, pink to red-brown scaly plaque representing a host immunological response to a variety of precursor lesions. LK is often misdiagnosed as a dermatological malignancy owing to its clinical resemblance to basal cell carcinoma (BCC) or Bowen disease. We performed a retrospective analysis of the pathology records of a series of LK lesions with reference to the demographic features and accuracy of clinical diagnosis. The pathology records from 2008 to 2009 of 263 consecutive patients with a histological diagnosis of LK from a specialized skin laboratory were retrieved. Data relating to clinical diagnosis, age, sex, anatomical location, time of year of presentation and any coexistent pathological lesions adjacent to the LK were recorded. Mean age at presentation was 64 years (range 34-96), and 58% of patients were female. The most common anatomical site was the chest/anterior torso, followed by the back and legs. The most common coexisting lesion was solar keratosis at 14%, followed by seborrhoeic keratosis (SK) at 7.8%. The correct clinical diagnosis of LK was made in 29.5% of cases. The most common clinical diagnosis was BCC (47%), while SK was the preferred diagnosis in 18%. A clinical diagnosis was not given in 5.5% of cases. In conclusion, it appears that LK is frequently misdiagnosed, with misdiagnosis occurring in > 70% of cases in this study. © 2017 British Association of Dermatologists.

    The extraoral sinus tract may occur as a result of an inflammatory process associated with a necrotic pulp. However, several non-odontogenic disorders may also produce an extraoral sinus tract. Thus, the differential diagnosis of this clinical finding is of paramount importance in providing appropriate clinical care because misdiagnosis of this condition may result in healing failure or unnecessary treatment. This case report of a 19-yr-old male patient describes an extraoral cutaneous sinus tract misdiagnosed as an endodontic lesion. Consequently, the patient underwent unnecessary exploratory procedures and antibiotic therapy. Identification of the inflammatory source of the lesion and removal of the affected tissue led to tissue healing.

    2012-11-01

    Narcolepsy is characterized by recurrent brief attacks of irresistible sleepiness. Signs can begin during childhood. However, diagnoses are frequently delayed by 10-15 years because of unfamiliarity with pediatric narcolepsy and variable presentations of its associated features (cataplexy, hypnagogic/hypnopompic hallucinations, and sleep paralysis). Therefore, patients may remain untreated during their formative years. Three children with narcolepsy who were initially misdiagnosed are described. Each child's signs were initially related to depression, hypothyroidism, jaw dysfunction, or conversion disorder. However, after a multiple sleep latency test, the diagnosis of narcolepsy was established. All three patients were treated appropriately with stimulant medications, selective serotonin reuptake inhibitors, or sodium oxybate, and demonstrated positive responses. Although no definitive cure exists for narcolepsy, early recognition and appropriate symptomatic treatment with medications can allow affected children to improve quality of life and achieve normality, both academically and socially.

    Adenoid cystic carcinoma is a rare malignant tumor that usually arises in the major and minor salivary glands and other locations containing secretory glands, including the lower female genital tract. Lower female genital tract carcinomas with adenoid cystic differentiation can be subclassified into 2 distinct groups based on the presence or absence of high-risk HPV. Cervical mixed carcinomas with some adenoid cystic differentiation are high-risk HPV-related but pure adenoid cystic carcinomas of vulvar and cervical origin appear to be unrelated to high-risk HPV. Mechanisms by which normal cells give rise to an HPV-unrelated adenoid cystic carcinoma remain largely unknown. Studies demonstrate that chromosomal translocation involving the genes encoding the transcription factors MYB and NFIB functions as a driving force of adenoid cystic carcinomas development regardless of anatomic site. The current study used fluorescence in situ hybridization with 3 different probes including MYB break-apart probe, NFIB break-apart probe, and MYB-NFIB fusion probe to assess for the presence of gene rearrangements in adenoid cystic carcinomas of the vulva. Six (66.7%) of 9 vulvar adenoid cystic carcinomas demonstrated NFIB rearrangement. Of these 6 cases with a disturbed NFIB, only 2 cases (33.3%) were positive for a MYB rearrangement that was also confirmed by a positive MYB-NFIB fusion pattern. NFIB-associated gene rearrangement is a frequent genetic event in vulvar adenoid cystic carcinomas. Chromosome translocations involving NFIB but with an intact MYB indicate the presence of novel oncogenic mechanisms for the development of adenoid cystic carcinomas of the vulva.

    We aimed to evaluate nonendodontic periapical lesions clinically misdiagnosed as endodontic periapical pathoses in a population of Taiwanese patients. Cases (2000-2014) of histopathological diagnoses of nonendodontic periapical lesions were retrieved from all cases with a clinical diagnosis of radicular cyst, apical granuloma, or apical periodontitis in the institution. These cases were regarded as misdiagnosed nonendodontic periapical lesions, of which the types and frequencies, in addition to the demographic data, were determined. Four thousand and four specimens were clinically diagnosed as endodontically associated pathoses, of which 118 cases (2.95%) received a histopathological diagnosis of a nonendodontic pathologic entity, the most frequent lesion being keratocystic odontogenic tumor (KCOT, n = 38, 32.20%), followed by fibro-osseous lesion (n = 18, 15.25%), and dentigerous cyst (n = 13, 11.02%). Nine malignant lesions in the periapical area [squamous cell carcinoma (n = 7, 5.93%), adenoid cystic carcinoma (n = 1, 0.85%), and Langerhans cell histiocytosis (n = 1, 0.85%)] were also noted. A wide variety of histopathological diagnoses, including benign odontogenic and non-odontogenic cystic and tumorous lesions and infectious diseases, as well as malignant lesions, was noted in these 118 cases of nonendodontic periapical lesions. Squamous cell carcinoma was the most predominant malignancy of nonendodontic periapical lesions misdiagnosed as apical periodontitis lesions from imaging examination overlooking the clinical findings. The current data form a useful basis for clinicopathological investigation and educational teaching regarding nonendodontic periapical lesions misdiagnosed as endodontic apical periodontitis lesions.

    Neoplasm of the vulva is a rare malignancy accounting for <5% of all female genital-tract cancer. However, in recent years the incidence of vulva intraepithelial neoplasia, known to serve as a precursor to carcinoma, has increased in young women generating considerable interest in its pathogenesis. Genetic changes at the molecular level in precursor or invasive vulvar tumors are not well investigated, and DNA copy number changes have not been reported until now. We used comparative genomic hybridization (CGH) to analyze genetic alterations in 10 primary invasive squamous cell carcinomas of the vulva. Chromosomal aberrations were identified in 8/10 cases. The most frequent chromosomal losses were 4p13-pter (five cases), 3p (four cases), and 5q (two cases), and less frequent losses were detected at 6q, 11q, and 13q (one case each). The most frequent chromosomal gains were 3q (four cases) and 8p (three cases), and less frequent gains were found in 9p, 14, 17, and 20q (one case each). The pattern of chromosomal imbalance in vulvar cancer detected by CGH was revealed to be very similar to that in cervical cancers, despite regional differences in their prevalence. These results suggest that the pathogenic pathways in vulvar and cervical carcinomas may be similar and that the genetic background may be common to these two squamous cell carcinomas.

    The Rab7 GTPase regulates late endosome trafficking of the Epidermal Growth Factor Receptor (EGFR) to the lysosome for degradation. However, less is known about how Rab7 activity, functioning late in the endocytic pathway, affects EGFR signaling. Here we used Caenorhabditis elegans vulva cell fate induction, a paradigm for genetic analysis of EGFR/Receptor Tyrosine Kinase (RTK) signaling, to assess the genetic requirements for rab-7. Using a rab-7 deletion mutant, we demonstrate that rab-7 antagonizes LET-23 EGFR signaling to a similar extent, but in a distinct manner, as previously described negative regulators such as sli-1 c-Cbl. Epistasis analysis places rab-7 upstream of or in parallel to lin-3 EGF and let-23 EGFR. However, expression of gfp::rab-7 in the Vulva Presursor Cells (VPCs) is sufficient to rescue the rab-7(−) VPC induction phenotypes indicating that RAB-7 functions in the signal receiving cell. We show that components of the Endosomal Sorting Complex Required for Transport (ESCRT)-0, and -I, complexes, hgrs-1 Hrs, and vps-28, also antagonize signaling, suggesting that LET-23 EGFR likely transits through Multivesicular Bodies (MVBs) en route to the lysosome. Consistent with RAB-7 regulating LET-23 EGFR trafficking, rab-7 mutants have increased number of LET-23::GFP-positive endosomes. Our data imply that Rab7, by mediating EGFR trafficking and degradation, plays an important role in downregulation of EGFR signaling. Failure to downregulate EGFR signaling contributes to oncogenesis, and thus Rab7 could possess tumor suppressor activity in humans. PMID:22558469

    The authors suggest a therapeutic scheme for carcinomata (intra-epithelial, micro-invasive and invasive) of the vulva after reviewing the literature and in the light of their own experience. It seems to them that treatment of these cancers can be carried out in the following way: Intra-epithelial cancers: partial vulvectomy for localised lesions or when treatment should be as conservative as possible. Total vulvectomy, or better still, superficial vulvectomy in other cases. Micro-invasive carcinomata: where the invasion is less than 2 mm: only total vulvectomy. Where the invasion is more than 2 mm: total vulvectomy with bilateral superficial lymphadenectomy. This is carried out as a complete lymphadenectomy when the lymph glands are found to be affected in the operating theatre. Invasive carcinomata: we exclude metastatic cancers where the local treatment is only carried out to give some palliation to the patient and sometimes can be combined with chemotherapy when that is possible. Patients that are operable: total vulvectomy with of course bilateral lymphadenectomy. This can be extended to iliac chains when Cloquet's gland is invaded. Radiotherapy after operation is to be discussed seeing that there are important sequelae from this. Lymph gland involvement can be unilateral in cases of N- stage I unilateral patients. Pelvic exenteration is only to be considered for young women who are in good general health and who have no pelvic metastases.

    The aim of our study was to review our experience with Paget's disease of the vulvar relative to initial examination, treatment and oncological outcome. Ten women with extramammary Paget's diseases of the vulva were treated during the 10-year period. The charts of these patients were reviewed and data were collected regarding patient demographics, symptoms, previous Paget's disease, surgical treatments and time to recurrence. Eight women (80%) were treated with wide local excision or partial vulvectomy, and two patients (20%) required radical resection for invasive adenocarcinoma. The group of women who had invasive diseases also underwent inquinofemoral lymphadenectomy and no lymphatic metastases were noted. Three women (30%) experienced recurrence. The mean time to relapse was 30 months (range 3-88 months). Recurrence is very common and long-term monitoring is recommended with careful examination of any abnormal vulvar lesion.

    Ossifying fibroma mimicking chronic apical periodontitis is extremely rare. This report describes a case of ossifying fibroma located in the periapical region of the mandibular right canine that was misdiagnosed as chronic apical periodontitis. A 40-year-old woman complained of slight pain in the right anterior mandibular region without mucosal abnormalities or swelling. Radiographically, a well-circumscribed, unilocular, radiolucent lesion was observed that was located in the periapical region of the mandibular right canine, which presented an endodontically treated root canal. Under local anesthesia, the lesion was fully excised. Microscopically, there was fibrocellular connective tissue associated with a mineralized component, which consisted of lamellar or trabecular and woven bone, compatible with the diagnosis of ossifying fibroma. Although it is very rare, ossifying fibroma should be considered in the differential diagnosis of unusual or persistent apical radiolucencies. Copyright (c) 2010 American Association of Endodontists.

    At present, cardiac metastasis of hepatocellular carcinoma is rarely mentioned in the literature. We report a hepatocellular carcinoma patient with cardiac metastasis misdiagnosed as hypertrophic cardiomyopathy in 2011. Two years later, on presentation of syncope, an abnormal ventricular septal size was recorded by ultrasound scan, and was subsequently shown by magnetic resonance imaging to be a tumour lesion. A myocardial biopsy confirmed infiltration of hepatocellular carcinoma. This observation underlines the risk of hepatocellular carcinoma cardiac metastasis, manifested in its infiltrative form as hypertrophic cardiomyopathy. In conclusion, we suggest that the ultrasound appearance of hypertrophic cardiomyopathy in hepatocellular carcinoma patients should be seen as a "red flag" and recommend the introduction of magnetic resonance imaging assessment of transplant candidates.

    Spinal dural arterio-venous fistula (SDAVF) is an uncommon and easily misdiagnosed vascular malformation. We aimed to report the diagnosis and management of a case with SDAVF. A 62-year-old man suffered from acute paraparesis about 15 months before this study. He underwent a neurosurgical procedure for herniated discs of the cervical spine at that time but there was no relief and the symptoms worsened despite the surgery. Neurologically, he had spastic paraparesis and decreased vibration sensation of the lower limbs. Spinal magnetic resonance imaging (MRI) revealed intra-medullary hyper-intensity lesion at T8 to T10 levels and tubular-like signal void structures in the corresponding posterior sub-arachnoid space. Further trans-arterial angiography through right T6 intercostal artery catheterization revealed engorged veins, thereby confirming the diagnosis of SDAVF. The patient was treated via endovascular embolization (18% Onyx, EV3TM MIT, Bonn, Germany) through spinal angiography and the results showed a marked decrease in engorged veins. After a 4-month follow-up, the patient was symptomatic but stable. Follow-up MRI showed a complete disappearance of the hyper-intensity change of the spinal cord. Spinal MR angiography did not reveal any recurrence of SDAVF. This case study demonstrated the easily misdiagnosed state of SDAVF. Serial neuroimage studies including spinal MRI, endovascular embolization through spinal angiography and MR angiography can be useful tools for its diagnostic confirmation, management and follow-up study.

    Langerhans cell histiocytosis (LCH) of the vulva is rare and even moreso in postmenopausal women. Twenty-six cases of primary vulvar LCH have been described in the current literature, and only 8 cases are in postmenopausal women. We report an additional case of primary vulvar LCH in a 59-yr-old woman with subsequent multiorgan involvement. In this article, we briefly describe the clinical presentation, histopathological findings, and immunohistochemistry results of vulvar LCH. We want to emphasize the importance of recognizing this entity in a woman with vulvar lesions both for the clinician and the pathologist.

    In Caenorhabditis elegans, the identification of many enzymes involved in the synthesis and modification of glycosaminoglycans (GAGs), essential components of proteoglycans, has attained special attention in recent years. Mutations in all the genes that encode for GAG biosynthetic enzymes show defects in the development of the vulva, specifically in the invagination of the vulval epithelium. Mutants for certain heparan sulfate modifying enzymes present axonal and cellular guidance defects in specific neuronal classes. Although most of the enzymes involved in the biosynthesis and modification of heparan sulfate have been characterized in C. elegans, little is known regarding the core proteins to which these GAGs covalently bind in proteoglycans. A single syndecan homologue (sdn-1) has been identified in the C. elegans genome through sequence analysis. In the present study, we show that C. elegans synthesizes sulfated proteoglycans, seen as three distinct species in western blot analysis. In the sdn-1 (ok449) deletion mutant allele we observed the lack of one species, which corresponds to a 50 kDa product after heparitinase treatment. The expression of sdn-1 mRNA and sequencing revealed that sdn-1 (ok449) deletion mutants lack two glycosylation sites. Hence, the missing protein in the western blot analysis probably corresponds to SDN-1. In addition, we show that SDN-1 localizes to the C. elegans nerve ring, nerve cords and to the vulva. SDN-1 is found specifically phosphorylated in nerve ring neurons and in the vulva, in both wild-type worms and sdn-1 (ok449) deletion mutants. These mutants show a defective egg-laying phenotype. Our results show for the first time, the identification, localization and some functional aspects of syndecan in the nematode C. elegans.

    A 64-year-old woman with recurrence of carcinoma of the vulva in an irradiated area received an en-bloc total pelvic exenteration. Reconstruction of the pelvic defect was performed with an anterolateral thigh (ALT) flap and a rectus abdominis muscle (RAM) flap (PM/RAM). This combination of flaps is unique, with excellent results. In a large defect, often irradiated in advance, well-vascularised tissue should be placed. Multiple flaps can be used to reconstruct these large pelvic defects, each with their own advantages and disadvantages. The combination of flaps used in this case uses the good properties of both flaps: the reliable and well-vascularised PM/RAM in combination with the ALT flap to provide much bulk in extreme large defects.

    Fungal diseases of vulva and vagina attributed to Candida species (vulvovaginal candidosis) are the most frequent mycoses of women. They show acute or chronic courses and different disease patterns which can strongly affect the quality of life of the women who are concerned. In general, the most common cause of acute vulvovaginal candidosis is Candida albicans, followed by C. glabrata. In chronic recurrent vulvovaginal candidosis, C. albicans and C. glabrata are often equally distributed. In several cases, treatment requires an antimycotic therapy which refers to the severity and main form of disease as well as to the aetiological agent. Most vulvovaginal candidoses are accessible to the treatment with local and systemic antimycotic agents. Generally, in Germany azoles such as clotrimazole, fluconazole and itraconazole, the polyens nystatin and Amphotericin B and the hydroxypyridone derivative ciclopirox are available for antimycotic therapy of vulvovaginal candidoses. Significance of non-conventional and adjuvant therapeutic approaches is considered to be generally low.

    Compared with left suprarenal splenosis, a right suprarenal accessory spleen is more likely to be misdiagnosed as an adrenal tumor because of its extreme rarity. Especially when splenosis mimics an atypical pheochromocytoma, preoperative diagnosis may become more difficult and elusive. Herein we report the case of a female patient with a right suprarenal mass, which was suspected to be an atypical pheochromocytoma based on a history of the classic triad and positive somatostatin receptor scintigraphy, but histopathology suggested a final diagnosis of right suprarenal splenosis.

    Twelve adolescents found to be the most problematic, crisis prone, and treatment resistant were comprehensively reevaluated in the special educational day school and treatment program they were attending. This reevaluation took place over a 6-month period and was done to arrive upon a more comprehensive diagnostic understanding so that more relevant and effective treatment measures could be instituted. The author conducted semistructured interviews with the adolescents on multiple occasions as the clinical situations warranted. All information available, recorded or otherwise, was comprehensively reviewed and reevaluated. The children were observed informally in and out of their classrooms throughout the period. All parents available were interviewed to clarify the children's present and past symptomatology and to assess the nature of psychiatric disorders, if any, in first- and second-degree family members. The reevaluation showed that 8 of the 12 youngsters clearly satisfied DSM-III-R criteria for bipolar disorder, which had been misdiagnosed mainly as attention-deficit hyperactivity disorder (ADHD) and conduct disorder. Three other youngsters showed significant bipolar features though not fully satisfying the criteria for this disorder. Bipolar disorder may be very common among highly problematic adolescents in special educational and outpatient treatment facilities for emotionally disturbed youngsters but may still be misdiagnosed very often as ADHD and conduct disorder, with all the negative consequences of such misdiagnosis.

    Vulvar cancer accounts for approximately 4% of gynecological malignancies. At the Instituto Nacional de Cancerologia in Mexico it occupies the fourth place. The purpose of this study is to assess the management of squamous carcinoma of the vulva with initial surgical treatment. It is a descriptive retrospective, observational study, from January 1, 2002 to December 31, 2012. Twenty-seven patients, clinical stages I, II, or III, initial surgical management, with at least one year of follow-up were included. In 51.85% a partial vulvectomy was performed and in 40.74% a wide excision; 66.66% underwent inguinofemoral dissection. Recurrence occurred in 25.91% of cases and the overall survival at 10 years was 63%. It is concluded that with invasion of up to 1 mm of lymph node, affection is 0%; with invasion of 1 mm and up to 5 mm this increases to 25%; an invasion of more than 5 mm implies up to 45%. Recurrence in our study was primarily distant, necessitating long-term monitoring with emphasis on symptoms to request imaging studies when suspected. Adjuvant therapy should be offered to patients with positive nodes, close or positive margins, and tumors larger than 4 cm.

    The aim of this study was to assess the clinicopathologic characteristics of patients with Paget's disease of the vulva who were treated by our gynecologic oncology service between 1985 and 2010. Vulvar Paget's disease patient demographics, pathologic diagnosis, treatment and follow-up data were reviewed over a 25-year period. The vulvar Paget's disease patients were primarily (62.5%) treated with a partial simple vulvectomy. Three patients had a history of malignancy, although none of them was intercurrent. Eleven patients had microscopically positive margins, 5 of whom developed progressive disease. Conversely, 5 patients had negative margins, of whom 4 had recurrent disease. There was a significant relationship between the presence of invasive disease and patient progression-free interval (PFI) (p = 0.007), but margin status and lesion size did not correlate with PFI (p > 0.05). Median patient PFI and follow-up was 30 and 53 months, respectively. We found a significant relationship between the presence of invasive disease and patient PFI in vulvar Paget's disease although the presence of microscopic positive margins and lesion size were not prognostic indicators. In patients with high risk factors, prolonged surveillance should be considered an essential component of optimal patient management.

    Crusted scabies is a severe, highly contagious form of classic scabies caused by the mite Sarcoptes scabiei var hominis . Crusted scabies is more common in immunosuppressed populations and overcrowded environments. In this condition, the host's immune system is overwhelmed and unable to defend against the mites on the skin, resulting in hyperinfestation of the host. Diagnosis can be challenging because the condition resembles other common skin conditions, such as plaque psoriasis. Furthermore, delayed diagnosis and inappropriate treatment can lead to worsening of the condition. We report a case of crusted scabies that was initially misdiagnosed in a 34-year-old incarcerated man with multidrug-resistant human immunodeficiency virus/AIDS. The patient had a complicated but complete recovery after treatment with permethrin and ivermectin was instituted.

    Angiomyofibroblastoma (AMF) is a benign mesenchymal tumor usually found in the vulva. We reviewed 70 cases of vulvar AMF that have been reported in the English-language literature and report 1 case of a pedunculated variant. Our case brings the total reported to 71 and is only the fourth pedunculated variant reported. This 50-year-old woman presented to our gynecology clinic with a 1-year history of a left labial mass. It began as pea-sized, and rapidly grew to 12 cm in diameter. Physical examination demonstrated a 12-cm pedunculated soft mass arising from the left labia majora. The clinical diagnosis was aggressive angiomyxoma, and a simple excision was performed. The final pathology demonstrated AMF. The patient remains free from tumor at 4 years of follow-up. Seventy-one cases were summarized. The mean age at presentation was 45 years. The lesions were equally distributed between the left (52%) and right (48%). The most common clinical diagnosis was a Bartholin gland cyst (46%) or lipoma (15%). The mean duration of the lesion before seeking treatment was 29 months, and the mean diameter at presentation was 5.9 cm. All of the patients were treated with simple excision. The mean duration of follow-up was 37 months. There was 1 report of sarcomatous transformation 2 years after initial treatment. Angiomyofibroblastoma is a rare benign tumor that most often occurs in the vulva. Differential diagnosis may include aggressive angiomyxoma, Bartholin cyst, or lipoma. The treatment of choice is simple total excision, which is usually curative.

    Thrombotic thrombocytopenic purpura (TTP) has a devastating prognosis without adapted management. Sources of misdiagnosis need to be identified to avoid delayed treatment. We studied 84 patients with a final diagnosis of severe (<10%) acquired ADAMTS13 deficiency-associated TTP from our National database that included 423 patients, who had an initial misdiagnosis (20% of all TTP). Main diagnostic errors were attributed to autoimmune thrombocytopenia, associated (51%) or not (37%) with autoimmune hemolytic anemia. At admission, misdiagnosed patients were more frequently females (P = .034) with a history of autoimmune disorder (P = .017) and had organ involvement in 67% of cases; they had more frequently antinuclear antibodies (P = .035), a low/undetectable schistocyte count (P = .001), a less profound anemia (P = .008), and a positive direct antiglobulin test (DAT) (P = .008). In multivariate analysis, female gender (P = .022), hemoglobin level (P = .028), a positive DAT (P = .004), and a low schistocytes count on diagnosis (P < .001) were retained as risk factors of misdiagnosis. Platelet count recovery was significantly longer in the misdiagnosed group (P = .041) without consequence on mortality, exacerbation and relapse. However, patients in the misdiagnosed group had a less severe disease than those in the accurately diagnosed group, as evidenced by less organ involvement at TTP diagnosis (P = .006). TTP is frequently misdiagnosed with autoimmune cytopenias. A low schistocyte count and a positive DAT should not systematically rule out TTP, especially when associated with organ failure. © 2017 Wiley Periodicals, Inc.

    Sebaceous gland hyperplasia is a common skin condition, very rarely reported in the female genital region. We present 13 cases from 12 patients, the first case series of sebaceous gland hyperplasia of the vulva. Differences in age at presentation and clinical presentation compared with classic sebaceous gland hyperplasia from the head and neck region were noted. Also, it was rarely included in the clinical differential diagnosis. Immunohistochemical studies to determine any possible association with the Muir-Torre syndrome were performed and mismatch repair protein loss was not identified.

    Introduction Favus of the scalp or tinea capitis favosa is a chronic dermatophyte infection of the scalp. In almost cases, favus is caused by Trichophyton schoenleinii, anthropophilic dermatophyte. It is characterized by the presence of scutula and severe alopecia. Besides the classic clinical type of tinea capitis favosa, there are many variant of clinical form which may persist undiagnosed for many years. In this work, we report an atypical form of favus to Trichophyton schoenleinii which was misdiagnosed as tinea amiantacea. Case-report An 11-year old girl came to the outpatient department of dermatology (day 0) with history of tinea amiantacea treated unsuccessfully with keratolytic shampoo (day – 730). She presented a diffuse scaling of the scalp with thick scaly patches and without scutula or alopecia. A diagnosis of tinea favosa by T. schoenleinii was made by mycological examination. She was treated with griseofulvin and ketoconazole in the form of foaming gel for twelve weeks. Despite treatment, clinical evolution was marked by appearance of permanent alopecia patches. The follow-up mycological examination was negative. Conclusion Because of ultimate evolution of favus into alopecia, we emphasize the importance of mycological examination in case of diffuse scaling.

    Chromatin modification genes play crucial roles in development and disease. In Caenorhabditis elegans, the class I histone deacetylase family member hda-1, a component of the nucleosome remodeling and deacetylation complex, has been shown to control cell proliferation. We recovered hda-1 in an RNA interference screen for genes involved in the morphogenesis of the egg-laying system. We found that hda-1 mutants have abnormal vulva morphology and vulval-uterine connections (i.e., no uterine-seam cell). We characterized the vulval defects by using cell fate-specific markers and found that hda-1 is necessary for the specification of all seven vulval cell types. The analysis of the vulval-uterine connection defect revealed that hda-1 is required for the differentiation of the gonadal anchor cell (AC), which in turn induces ventral uterine granddaughters to adopt π fates, leading to the formation of the uterine-seam cell. Consistent with these results, hda-1 is expressed in the vulva and AC. A search for hda-1 target genes revealed that fos-1 (fos proto-oncogene family) acts downstream of hda-1 in vulval cells, whereas egl-43 (evi1 proto-oncogene family) and nhr-67 (tailless homolog, NHR family) mediate hda-1 function in the AC. Furthermore, we showed that AC expression of hda-1 plays a crucial role in the regulation of the lin-12/Notch ligand lag-2 to specify π cell fates. These results demonstrate the pivotal role of hda-1 in the formation of the vulva and the vulval-uterine connection. Given that hda-1 homologs are conserved across the phyla, our findings are likely to provide a better understanding of HDAC1 function in development and disease.

We found that hda-1 mutants have abnormal vulva morphology and vulval-uterine connections (i.e., no uterine-seam cell). We characterized the vulval defects by using cell fate-specific markers and found that hda-1 is necessary for the specification of all seven vulval cell types. The analysis of the vulval-uterine connection defect revealed that hda-1 is required for the differentiation of the gonadal anchor cell (AC), which in turn induces ventral uterine granddaughters to adopt π fates, leading to the formation of the uterine-seam cell. Consistent with these results, hda-1 is expressed in the vulva and AC. A search for hda-1 target genes revealed that fos-1 (fos proto-oncogene family) acts downstream of hda-1 in vulval cells, whereas egl-43 (evi1 proto-oncogene family) and nhr-67 (tailless homolog, NHR family) mediate hda-1 function in the AC. Furthermore, we showed that AC expression of hda-1 plays a crucial role in the regulation of the lin-12/Notch ligand lag-2 to specify π cell fates. These results demonstrate the pivotal role of hda-1 in the formation of the vulva and the vulval-uterine connection. Given that hda-1 homologs are conserved across the phyla, our findings are likely to provide a better understanding of HDAC1 function in development and disease. PMID:23797102

    To determine influence of vestibulovaginal stenosis, pelvic bladder, and recessed vulva on response to treatment for clinical signs of lower urinary tract disease in dogs. Retrospective study. 38 spayed female dogs. Medical records and client follow-up were reviewed for dogs evaluated via excretory urography because of clinical signs of lower urinary tract disease. Clinical signs, results of radiography, and response to surgical or medical treatment were analyzed. Clinical signs included urinary tract infection (n = 24), urinary incontinence (20), vaginitis (11), pollakiuria or stranguria (10), and perivulvar dermatitis (4). Vaginocystourethrographic findings included vestibulovaginal stenosis (n = 28), pelvic bladder (17), and ureteritis or pyelonephritis (4). Ten dogs had a vestibulovaginal ratio of < 0.20 (severe stenosis), 9 dogs had a ratio of 0.20 to 0.25 (moderate stenosis), 9 dogs had a ratio of 0.26 to 0.35 (mild stenosis), and 10 dogs had a ratio of > 0.35 (anatomically normal). Lower urinary tract infection, incontinence, and pelvic bladder were not associated with response to treatment for recessed vulva. Vestibulovaginal stenosis with a ratio < 0.20 was significantly associated negatively with response to treatment. Dogs without severe vestibulovaginal stenosis that received vulvoplasty for a recessed vulva responded well to treatment. Vestibulovaginal stenosis is likely an important factor in dogs with vestibulovaginal ratio < 0.20. Vaginectomy or resection and anastomosis should be considered in dogs with severe vestibulovaginal stenosis and signs of lower urinary tract disease.

    Summary Background Nodular fasciitis of the breast is a rare benign pathology that can mimic breast cancer clinically, radiologically, and histopathologically. Case Report An 18-year-old female patient had first visited a physician in a different center with the complaint of a lump in her left breast. Breast examination had revealed a palpable mass located in the left upper outer quadrant. Ultrasonography had demonstrated a hypoechoic lesion. Excisional biopsy of the lump had been performed and histopathologic examination misdiagnosed this lump as a mesenchymal tumor. The patient was then referred to our clinic for further investigations. Pathologic revision was performed and the diagnosis of nodular fasciitis of the breast was established. Conclusion Awareness of this rare clinical entity, nodular fasciitis, in the breast eliminates the misdiagnosis of breast cancer. PMID:20877676

    Primary adenocarcinoma of the vulva, unrelated to the native glands of perineum is an extremely rare neoplasm. Despite awareness of this lesion for over 40 years, the origin is not beyond speculation. The most reasonable hypothesis is based on the remnants of cloacal differentiation during early days of life. Here we report the case of a 60-year-old patient with a vulvar mass, who underwent partial vulvectomy and bilateral regional lymph node dissection. The tumor was composed of papillary and complex glandular structures and exhibited diffuse positivity for cytokeratin 20 and polyclonal CEA, CDX2, and focal positivity with cytokeratin 7. Unlike the indolent behavior of this malignant neoplasm according to the literature, we found two metastatic inguinal lymph nodes. She did not receive adjuvant therapy and is still alive, free of disease 38 months after surgery. We present different aspects of vulvar adenocarcinomas with a case report.

    Several clinical-pathological parameters have been related to survival of patients with invasive squamous cell carcinoma of the vulva, whereas few studies have investigated the ability of biological variables to predict the clinical outcome of these patients. The present paper reviews the literature data on the prognostic relevance of lymph node-related parameters, primary tumor-related parameters, FIGO stage, blood variables, and tissue biological variables. Regarding these latter, the paper takes into account the analysis of DNA content, cell cycle-regulatory proteins, apoptosis-related proteins, epidermal growth factor receptor [EGFR], and proteins that are involved in tumor invasiveness, metastasis and angiogenesis. At present, the lymph node status and FIGO stage according to the new 2009 classification system are the main predictors for vulvar squamous cell carcinoma, whereas biological variables do not have yet a clinical relevance and their role is still investigational.

    This report describes a case of vocal cord dysfunction at first misdiagnosed as reactive airway dysfunction syndrome (RADS). A woman developed recurrent episodes of cough, dyspnea, and wheezing unresponsive to asthma therapy after irritant exposure to glutaraldehyde. Direct laryngoscopy was performed immediately after the induction of symptoms. Laryngoscopy showed a paradoxical adduction of the vocal cord on inspiration. Vocal cord dysfunction was diagnosed. A case of vocal cord dysfunction occurred after exposure to glutaraldhyde in a person with a history highly suggestive of RADS. Vocal cord dysfunction should always be considered in the differential diagnosis of patients with acute respiratory symptoms after exposure to irritants and with asthma-like symptoms that fail to respond to conventional asthma therapy.

    The aim of the study was to evaluate the risk of recurrence according to the surgical margin status and the presence of invasion or of superficially invasive carcinoma in patients with extramammary Paget disease (EMPD) of the vulva, who underwent elective surgical treatment. We performed a retrospective analysis of 27 patients with first diagnosis of extramammary Paget disease of the vulva, who underwent primary and elective surgical treatment from January 1989 to December 2014. A p value of less than .05 was considered statistically significant. Multivariable logistic regression was performed to adjust for confounding factors. We observed invasive disease in 11 cases, with microinvasion in 8 of them. A positive surgical margin was found in 10 patients. During a median follow-up period of 79.5 months, 8 patients (29.6%) showed a first recurrence after a median (range) time of 4.9 (2.3-7.1) years. No significant differences were observed between patients with recurrence and patients without recurrence with respect to age, number of vulvar sectors involved, bilaterality and multifocality, presence of invasion or microinvasion, and surgical margin status. However, during the follow-up period, the presence of invasion was higher (67% vs 41%) in patients with recurrence compared with patients without recurrence. The rate of recurrence of the disease after therapy is high. Patients should be subjected to a close and long-term follow-up to identify those who must undergo further treatment, especially if they presented with an invasive or even microinvasive disease. A free margin of no greater than 1 to 2 cm might be the most appropriate surgical choice.

    To review the diagnostic features and characteristics of an uncommon tumour, basal cell carcinoma (BCC) of the vulva. The clinical and pathological details of six vulvar BCCs were reviewed. Four of the BCCs arose in isolation, one was combined with vulvar Paget's disease and another was intimately associated with a poorly differentiated squamous cell carcinoma. The average age of the six patients was 76 years (75 years for 'isolated' BCC; 78 years for BCC 'mixed' with other lesions). The duration of symptoms averaged 13 months in 'isolated' BCC but 24 months in 'mixed' BCC. Vulvar pruritus was the most common presenting complaint in the four cases of 'isolated' BCC. The initial biopsies included shave (× 2) or punch biopsies (× 4). Definitive surgery included excisional biopsy (× 2) or a wide local excision (× 3). In the five assessable tumours, the maximum tumour diameter averaged 19.8 mm (range 11-36 mm). In the sixth patient the BCC was contiguous with a 70 mm, unresectable, poorly differentiated squamous cell carcinoma which was treated by radiotherapy alone. : Although the histological diagnosis of vulvar BCC was straightforward in some of our cases, others presented difficulties due to non-representative initial biopsies, insufficient clinical information or contiguity with lesions of greater clinical significance such as Paget's disease or squamous cell carcinoma.

    Primary melanomas of the vulva and vagina are rare. As a result, it has been difficult to develop evidence-based guidelines for their management. By analyzing a large series of patients with vulval and vaginal melanomas, this study sought to document the most common presenting features, identify clinical and pathologic predictors of outcome, and provide management guidelines. A clinicopathologic analysis of 85 patients with primary melanomas of the vulva or vagina diagnosed and treated at Melanoma Institute Australia and associated units in Sydney, Australia, between 1960 and 2011 was performed. Predictors of disease-free and melanoma-specific survival (MSS) were determined. Patients with American Joint Committee on Cancer (AJCC) stage 0-II had a significantly better MSS (5Y MSS = 63.6 %, n = 59) compared with those with stage III disease (5Y MSS = 0 %, n = 12, p < 0.001). Tumor thickness, ulceration status, and pathologic clearance margin were significant predictors of MSS. Disease-free survival was predicted by these factors and additionally by tumor mitotic rate. The results of this study provide evidence to support the appropriateness of utilizing the AJCC (7th edition) cutaneous melanoma staging system for vulval and vaginal melanomas. Detection and removal of these melanomas at an early stage with pathologically confirmed clear margins confers the best chance of cure.

    Bipartite patella is recognized as a developmental anomaly of ossification. Most of them are asymptomatic and are discovered incidentally. Bipartite patella is sometimes misdiagnosed as a patella fracture, because the x-ray images of both these conditions may appear very similar. In this case, the patient complained of left knee pain after x-ray films revealed a fracture-like line in the left patella. The patient was then diagnosed as having a patella fracture. In China, the injury degree is categorized as serious injury, minor injury, and trivial injury. As the injury degree of patellar fracture is identified as minor injury, the defendant who injured the patient will be sentenced to prison for ≤3 years. However, the defendant objected to this judgment and applied for the second evaluation of injury degree. On the basis of the site of injury, clinical manifestations, and imaging findings, we diagnosed the patient with bipartite patella which belongs to normal anatomic variant. Therefore, the injury degree of the patient was not minor injury. © 2017 American Academy of Forensic Sciences.

    Malignant tumors of the vulva, most of them squamous cell carcinomas, account for only 5% of cancers of the female genital tract. Though little is known about the genetic features of these tumors, the Fragile Histidine Triad (FHIT) and High Mobility Group AT-hook 2 (HMGA2) genes were found deregulated. We wanted to gain more knowledge about the expression of HMGA2-related miRNAs such as miR-30c and let-7a, and whether a correlation exists between the expression of FHIT and HMGA2, in this tumor type. An inverse correlation was found in-as-much as HMGA2 was highly expressed (mean fold change 8.8) whereas miR30c and let-7a were both downregulated (mean fold change -3.9 and -2.3, respectively). The consistent overexpression of HMGA2 found in all tumors adds to the likelihood that this gene is of importance in SCC pathogenesis. Moreover, we came to the conclusion that miRNAs may be the cause of the deregulation of HMGA2. Our results also show that SCC of the vulva presents a characteristic molecular pattern with FHIT being downregulated whereas HMGA2 is upregulated.

    Purpose To determine the safety of sentinel lymph node biopsy as a replacement for inguinal femoral lymphadenectomy in selected women with vulvar cancer. Patients and Methods Eligible women had squamous cell carcinoma, at least 1-mm invasion, and tumor size ≥ 2 cm and ≤ 6 cm. The primary tumor was limited to the vulva, and there were no groin lymph nodes that were clinically suggestive of cancer. All women underwent intraoperative lymphatic mapping, sentinel lymph node biopsy, and inguinal femoral lymphadenectomy. Histologic ultra staging of the sentinel lymph node was prescribed. Results In all, 452 women underwent the planned procedures, and 418 had at least one sentinel lymph node identified. There were 132 node-positive women, including 11 (8.3%) with false-negative nodes. Twenty-three percent of the true-positive patients were detected by immunohistochemical analysis of the sentinel lymph node. The sensitivity was 91.7% (90% lower confidence bound, 86.7%) and the false-negative predictive value (1-negative predictive value) was 3.7% (90% upper confidence bound, 6.1%). In women with tumor less than 4 cm, the false-negative predictive value was 2.0% (90% upper confidence bound, 4.5%). Conclusion Sentinel lymph node biopsy is a reasonable alternative to inguinal femoral lymphadenectomy in selected women with squamous cell carcinoma of the vulva. PMID:22753905

    Intrahepatic cholangiocarcinoma (ICC) or combined hepatocellular cholangiocarcinoma (cHCC-CC) is considered to be contraindications for liver transplantation (LT); however, recent studies have shown that the outcomes of LT in small incidental ICC/cHCC-CC tumors are comparable to those in HCC. Studies reporting the survival outcome of patient(s) undergoing LT and found to have incidental or misdiagnosed ICC and/or cHCC-CC in liver explants were reviewed. Our institutional data were also included in the review analysis. In this review, 21 studies reporting 19865 cases of liver transplantation were included. The incidence of misdiagnosed/incidental ICC/cHCC-CC in liver explants was found to be 0.7% (136/19636). Hepatitis B and C virus infection was reported in 19 and 47% of the cases, respectively. The recurrence rate after LT was 42%. The most common site for recurrence was extrahepatic (73%). The disease free survival rate at 3 years was reported to range 33-86%. The 3-year overall survival rate was reported be 22-70%. The outcome of LT in patients with incidental/misdiagnosed ICC/cHCC-CC was found to be poorer than that of matched patients with HCC in five studies; however, the outcome becomes equivalent to those of HCC in cases of small (<2 cm), well-differentiated ICC/cHCC-CC tumors without vascular invasion.

    Acral lentiginous melanoma (AML) does not exhibit the classic signs of malignant melanoma. ALM is frequently misdiagnosed because of its unusual sites and atypical clinical morphologies, which lead to poor prognosis. A female patient aged 78 years was presented to our center with two ulcers on her right foot. Diabetic foot ulcer was considered as the primary diagnosis. The ulcers failed to improve after 2 weeks' therapy. An incisional biopsy of the lesion revealed malignant melanoma. The patient received wide excision, skin grafting as well as biotherapy. The lesion was healed and no other metastasis has been founded until now. Clinicians must maintain a high level of suspicion in distinguishing malignant melanoma from other more benign skin lesions of the foot. The need for early biopsy of ulcer, even when clinical suspicion is low, can not be overemphasized. Only in this way can we reduce misdiagnosis rate and improve survival rate in patients with foot ulcer.

    Thyroid changes are considered to be normal events that happen as a large maternal multiorganic adjustment to pregnancy. However, hyperthyroidism occurs in pregnancy with clinical presentation similar to hyperemesis gravidarum (HG) and pregnancy itself. Moreover, 10% of women with HG will continue to have symptoms throughout the pregnancy suggesting that the underlying cause might not be elevation of human chorionic gonadotropin in the first trimester. Variable frequency of both hyperthyroidism and HG worldwide might suggest the puzzlement of inclusion criteria for both diagnoses enhanced by the alternation of thyroid hormone levels assessed in normal pregnancy. Increased number of hyperthyroidism among women population without the expected rise in gestational hyperthyroidism encouraged us for creating the hypotheses that hyperthyroidism could be underestimated in normal pregnancy and even misdiagnosed as HG. This hypothesis, if confirmed, might have beneficial clinical implications, such as better detection of hyperthyroidism in pregnancies, application of therapy when needed with the reduction of maternal or fetal consequences.

    Idiopathic pulmonary fibrosis (IPF), also known as cryptogenic fibrosing alveolitis, is one of a spectrum of idiopathic interstitial pneumonia. IPF is an increasingly common condition which poses many diagnostic and therapeutic challenges leading to misdiagnosis and mismanagement. We presented a 55-year-old male textile trader who was initially managed as sputum-negative pulmonary tuberculosis before histology report. He presented to our clinic with Breathlessness and cough of 3 years and 2.5 years, respectively. He had commenced anti-tuberculosis two months before presentation without significant relief. General Physical examination and vital signs were essentially normal. SPO2 was 96% on room air. Chest Examination revealed end-inspiratory bi-basal velcro-like crackles. Other systemic examinations were normal. Radiological examination by way of chest X- ray and chest CT showed features suggestive of IPF. The patient also had open Lung biopsy for histology and spirometry which demonstrated restrictive ventilatory function pattern. A diagnosis of Interstitial lung disease probably Idiopathic Pulmonary Fibrosis was entertained. He was commenced on Tab prednisolone, Tab Rabeprazole, with minimal improvement. IPF have often been misdiagnosed and treated as pulmonary tuberculosis with unfavorable outcome.

    The warty disordered lesions of the vulva in three female patients were diagnosed as Bowenoid papulosis on the basis of clinical and histopathological findings. In all three vulvar lesions, human Papillomavirus type 16 (HPV 16) DNA was identified hy Southern blot hybridization and Papillomavirus genus‐specific (PGS) antigen was detected in one case immunohistochemically. Furthermore, colposcopic examination revealed the presence of abnormal uterine cervical lesions in two cases. They were found to be intraepithelial neoplasia which harbored HPV 16 DNA and were positive for PGS antigen. PMID:2540130

    In the period from April 1987 to April 1990, 230 patients with pathological changes of the vulva, vagina and cervix uteri were treated with the CO2-laser. The diagnosis and pretreatment stages of the diseases were confirmed by the cytodiagnostic, colposcopic and histopathological results of the biophysics. In most cases, DNA-hybridization of human papilloma viruses confirmed their virus etiology. Twenty patients had peak condyloma of the vulva and vagina, 34 had benign cervical diseases, 65 were at the premalignant and 111 in the first stages of malignant cervical disease. Vaporizations, conical or cylindrical excisions were performed depending on the nature of disease and its localisation. The average age of operated patients was 30.6 years and the average parity 0.69. Operations were performed using analgesia and in rare cases total anesthesia. After the excision treatment, the tissue was checked histo-pathologically according to the principle of series. The complications were very rare. After operation, postoperative control was performed after 3.9 and 15 months, and later once a year. The results have shown that one treatment was sufficient in 80% of patients for curing vulvar and vaginal disease and 20% patients needed repeat because of the condyloma that relapsed. After the first treatment, benign and premalignant cervical diseases were cured in 100% of cases. In 95.4% operated patients at the first stages of cervical malignant diseases, the excisional treatment was final and in 4.6% needed an additional radical therapy because of a higher stage of lesion found by the conular histo-pathological analysis. There were no relapses relating to the cervix.

    Erythema migrans is the initial sign in the majority of patients infected with Borrelia, the genus of spirochetes that causes Lyme disease. Early identification and treatment decrease the risk of progression to later stages of disease. Although a "bull's eye" appearance owing to lesional clearing is considered classic for erythema migrans, this feature is surprisingly often lacking among patients in the United States. Furthermore, cutaneous Lyme disease can exhibit a wide range of morphologic variability in a minority of patients. Herein, we describe the case of a patient with Lyme disease in which the presence of atypical vesicular features, in conjunction with the initial absence of clearing, resulted in multiple misdiagnoses and delayed treatment. We also review the literature on the epidemiology and management of erythema migrans for cases in which the diagnosis may pose a challenge.

    To study and summarize the clinical features of hypophosphatemia osteomalacia (HO) misdiagnosed as spondyloarthritis (SpA), aiming to analyze the reasons of misdiagnosis and improve the prognosis of such patients. A total of 26 cases of HO misdiagnosed as SpA were selected. Clinical features, laboratory tests, and image presentations were analyzed. Related literatures were reviewed. (1) Clinical characters: 26 patients were included (12 males and 14 females) with a median age of 38 years (range 20-60). The mean disease duration was 3.2 years (range 0.75 to 10 years). Of all the patients, 15 were diagnosed as tumor-induced HO, 4 were long-term oral adefovir dipivoxil-related HO, 3 were associated with Fanconi syndrome, 2 were related to hyperparathyroidism, while 2 were Sjogren's syndrome complicated with renal tubular acidosis. All of the 26 patients presented with low back pain including 15 with night pain. The time of morning stiffness was about 30 minutes. Non-steroidal anti-inflammatory drugs were given to each patient whereas with poor efficacy, neither did other agents work well, such as glucocorticoids, disease modifying anti-rheumatic drugs and biologics. (2) LABORATORY FINDINGS: the platelet count and inflammatory markers such as erythrocyte sedimentation rate, C-reactive protein (CRP) were usually normal. The level of serum calcium was normal or slightly lower, nevertheless, all patients had hypophosphatemia and increased level of alkaline phosphatase (ALP). Patients with adefovir dipivoxil-related HO, Fanconi syndrome or Sjogren's syndrome complicated with renal tubular acidosis were characterized by hypokalemia, hyperchloremia and alkaline urine. Patients with hyperparathyroidism had elevated parathyroid hormone (PTH). Positive antinuclear antibodies (ANA) (titer ≥ 1: 320), anti-SSA/SSB antibodies were found in patients with Sjogren's syndrome. (3) Radiographic features: sacroiliac joint lesions were found in X-ray, CT, positron emission tomography

    Lymphoma is a malignant neoplasm of component cells of the lymphoid system which is very rare in the jaws. Here we report a case of primary diffuse large B-cell lymphoma located in the periapical region of a mandibular molar which was misdiagnosed as chronic periapical periodontitis. The present case was diagnosed at an early stage and effectively managed by chemotherapy. Although lymphoma of the mandible is rare, it must be considered in the differential diagnosis of radiolucent lesions in this region. Lack of knowledge of this rare presentation may lead to delays in diagnosis and poor prognosis. © 2013 Australian Dental Association.

    Granular cell tumor (GCT) usually occurs as a single tumor, although sometimes multiple lesions can occur. In present report we analyze the clinicopathological and immunohistochemical features of a multiple GCT involving the tongue of a 14-year-old girl, with no other abnormalities, with a metachronous occurrence of a second GCT in vulva, after a period of 10 years. Both tumors revealed S-100, vimentin and CD57 positivity. In addition, over expression of calretinin was observed in tumor cells located in the vicinity of pseudoepitheliomatous hyperplasia (PEH) of the tongue. Tumor vasculature situated close to the PEH showed marked CD105 reactivity, data not described so far, suggesting an interaction between PEH cells and underlying stroma, since GCT completely lacks CD105 vessels. Our study emphasizes that patients with GCT, especially young patients, should be followed long-term, looking for multiple tumors or other abnormalities suggestive of a systemic syndrome, given the associations described in multiple GCT.

    A 29-year-old Turkish woman with allergic contact cheilitis from a lipstick was misdiagnosed as herpes labialis and subsequently worsened with the application of Zovirax cream. Patch tests were positive to Zovirax cream, propylene glycol, the patient's favourite lipstick and propyl gallate. No reaction was seen with Zovirax ophthalmic ointment and Zovirax tablet. The propylene glycol component of the Zovirax cream and the propyl gallate component of the lipstick were regarded as the responsible contact sensitizers. The differential diagnosis was challenging due to concomitant contact sensitization with these agents.

    Cancer of the vulva is a rare condition that has been subject to limited research with a paucity of studies into the impact of this disease. Although the physical effects may readily be described, little is known about the psychological, emotional and social impact of this condition. To increase insights, a qualitative research study was undertaken to explore the experiences of women with vulval cancer living in the UK. An interpretive phenomenological approach based on the work of Heidegger and Van Manen was used to frame the study in which 13 women under 50 years of age were interviewed between 6 months and 5 years after their surgery. Data were analysed using framework analysis described by Ritchie and Spencer. This article describes the concept of aloneness which emerged from the data. This includes consideration of the women's sense of isolation due to the geographical distance between the woman's home and the hospital, and a sense of separation as they described their loss of sexual function and ability to enjoy the sexual relationship they had previously, following the onset of their symptoms of vulval cancer and subsequent treatment. The women's sense of aloneness was also manifest in their perception that there was a lack of knowledge and understanding about this condition both in their social world and the healthcare system in which they received treatment. © 2011 Blackwell Publishing Ltd.

    The current study describes a case of right coronary artery fistula (CAF) misdiagnosed as right atrial myxoma (RAM). A 33-year-old man presented with a 13-year history of intermittent chest pain, and aggravation for 3 days. Echocardiography revealed an occupying lesion in the right atrium producing a partial dynamic tricuspid obstruction. The initial diagnosis was RAM, which causes partial right ventricular inflow tract obstruction. During cardiopulmonary bypass surgery, a giant mass was detected in the anterior wall of the right ventricle and an abnormal vascular fistula was observed at the bottom of the mass. Successful excision of the mass and closure of the fistula completely relieved the patient's presenting symptoms. The disease was subsequently diagnosed as right CAF draining to the myocardial void. The surgical management and misdiagnosis of the case are discussed herein.

    Infectious pelvic inflammatory disease is a common condition and a frequent cause of abdominal pain in a young female patient. In a patient who has not completed family planning, the diagnosis is often made with a low threshold and treatment started on a low suspicion of diagnosis to avoid a negative impact on fertility. Here, we present a case of a 41-year-old woman who was misdiagnosed with infectious pelvic inflammatory disease and treated ineffectively with antibiotics when the underlying condition of her persistent abdominal pain was a midgut neuroendocrine tumor that had caused bowel perforation and formation of an abscess in the pouch of Douglas.

    Sebaceous glands are abundant on the vulva, but vulvar sebaceous carcinoma (SC) is an uncommon neoplasm. We report a case of SC of the vulva in a 51 year-old woman. The patient presented a 6-month history of an asymptomatic 2.5 x 1.5 cm exophytic tumour localized on the left labium majora. Tumorectomy was performed. Histologically, the lesion had an irregular lobular growth pattern composed of lobules or sheets of malignant cells separated by fibrovascular stroma. There was a mixture of sebaceous-type differentiation, small ducts and areas showing basaloid or squamous features. Centrally-located tumour cells showed moderate EMA immunoreactivity, especially enhancing cytoplasmic "bubbliness". Tumour cells were immunoreactive for CAM 5.2. The immunoreactivity for intranuclear p53 staining was > 10%. Southern blot hybridization and PCR studies did not detect HPV DNA. Hemivulvectomy was performed. After 18 months of follow-up, the patient has no evidence of recurrence, metastases or other malignant tumours. The grading of cutaneous SC proposed by Rutten et al. (World Health Organization Classification of Skin Tumours) and Patterson & Wick (Nonmelanocytic Tumours of the Skin. Armed Forces Institute of Pathology) is based on patterns of tumour growth rather than cytological features. Such grading of skin SC, including vulvar SC, should not be used since its prognostic value has not been sufficiently documented. As the number of reported vulvar SCs is very limited, their natural history is unknown and the optimal treatment has not been established. The follow-up of 7 reported cases supports the general opinion that the tumour may be aggressive. SC groin node metastases carry a devastating prognosis, and unrecognized disease in the inguinofemoral lymph nodes is nearly always fatal. The use of sentinel lymph nodes (SLN) has evolved as an effective surgical technique for identifying early subclinical regional nodal involvement for many solid tumours throughout the body for

    Xanthogranulomatous pancreatitis (XGP) is an extremely rare cause of a cystic pancreatic mass. The pathophysiology of this process is not entirely clear but likely results from a combination of duct obstruction, infection, and repeated hemorrhage. It is difficult to differentiate this inflammatory lesion from a cystic neoplasm and, therefore, in the majority of cases XGP is misdiagnosed as a neoplasm on preoperative imaging. In this report, we describe a case of XGP, the imaging characteristics of XGP, and a differential diagnosis for a cystic pancreatic lesion. Copyright © 2017 Elsevier Inc. All rights reserved.

    Peripheral primitive neuroectodermal tumor (PNET) of the vulva is an extremely rare disease, and, to our knowledge, only two cases have been previously reported. A 45-year-old woman presented with a mass in the right labium major. Three years after removal of the tumor, she noticed a new lesion in the same place and underwent a partial vulvectomy. The imprint cytology of the recurrent tumor showed a monomorphic appearance, composed of small round cells with scant cytoplasm against a hemorrhagic background. These tumor cells were loosely connective, but rosettelike structures were observed focally. On pathologic examination, the neoplasm was composed of small round tumor cells showing sinusoidal, diffuse or micropapillary growth. Immunohistochemically, the neoplastic cells stained positively for neuron-specific enolase, vimentin and HBA 71 and negatively for cytokeratin, HBA 45 and muscle-specific actin. The morphologic characteristics of the disease were well expressed in the imprint cytology, and this influenced the selection of immunohistochemical studies. Cytologic examination for vulvar tumors, even imprint cytology, can be a useful tool in obtaining an accurate pathologic diagnosis of a rare disease, such as peripheral PNET.

The lesion was localised at the right minor labium and was resected by partial vulvectomy. A synchronous sentinel lymph node biopsy revealed a single micrometastasis in the right inguinal region, which prompted local radiotherapy. Follow-up nine months later showed only slight vulvar atrophy, without signs of local recurrence or distant metastases. Although lymphoepithelioma-like carcinomas of the skin and the female genital tract are presumed to have a better prognosis than their counterparts in the upper aerodigestive tract, possibly due to earlier detection and therapy, this case documents their potential for early metastasis.

  3. The caenorhabditis elegans CDT-2 ubiquitin ligase is required for attenuation of EGFR signalling in vulva precursor cells

    PubMed Central

    2010-01-01

    Background Attenuation of the EGFR (Epidermal Growth Factor Receptor) signalling cascade is crucial to control cell fate during development. A candidate-based RNAi approach in C. elegans identified CDT-2 as an attenuator of LET-23 (EGFR) signalling. Human CDT2 is a component of the conserved CDT2/CUL4/DDB1 ubiquitin ligase complex that plays a critical role in DNA replication and G2/M checkpoint. Within this complex, CDT2 is responsible for substrate recognition. This ubiquitin ligase complex has been shown in various organisms, including C. elegans, to target the replication-licensing factor CDT1, and the CDK inhibitor p21. However, no previous link to EGFR signalling has been identified. Results We have characterised CDT-2's role during vulva development and found that it is a novel attenuator of LET-23 signalling. CDT-2 acts redundantly with negative modulators of LET-23 signalling and CDT-2 or CUL-4 downregulation causes persistent expression of the egl-17::cfp transgene, a marker of LET-23 signalling during vulva development. In addition, we show that CDT-2 physically interacts with SEM-5 (GRB2), a known negative modulator of LET-23 signalling that directly binds LET-23, and provide genetic evidence consistent with CDT-2 functioning at or downstream of LET-23. Interestingly, both SEM-5 and CDT-2 were identified independently in a screen for genes involved in receptor-mediated endocytosis in oocytes, suggesting that attenuation of LET-23 by CDT-2 might be through regulation of endocytosis. Conclusions In this study, we have shown that CDT-2 and CUL-4, members of the CUL-4/DDB-1/CDT-2 E3 ubiquitin ligase complex attenuate LET-23 signalling in vulval precursor cells. In future, it will be interesting to investigate the potential link to endocytosis and to determine whether other signalling pathways dependent on endocytosis, e.g. LIN-12 (Notch) could be regulated by this ubiquitin ligase complex. This work has uncovered a novel function for the CUL-4/DDB-1/CDT-2 E

    To generate an understanding of the women's own perspectives of their care and address a gap in knowledge in relation to the broader impact of vulval cancer. Few people go though life without experiencing events that can change their perspective on how they see themselves, their role in society and their relationship with those around them. People are multi-dimensional, so a person with has a physical illness is also affected psychologically and sociologically. Qualitative. Based on the work of Heidegger and van Manen, an interpretative phenomenological research study was undertaken to explore the experiences of thirteen women under 50 years of age with vulval cancer living in the UK. Data were analysed using framework analysis and showed that a diagnosis of cancer of the vulva and the subsequent treatment has an effect on physical, psychological and sexual functioning. The concept of 'All Change' expressed the sentiment that following the diagnosis and surgery, everything has changed; life is not the same as it was before diagnosis. This included both physical and psychological changes and impacts on perceptions of body image. The challenge is to raise awareness of vulval cancer among health care professions and society in general and determine the most effective interventions in facilitating pre and post operative support for these women. © 2012 Blackwell Publishing Ltd.

    2017-01-01

    Abstract Rationale: Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. Patient concerns: We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. Diagnoses: She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. Interventions: This patient was treated successfully with surgery. Outcomes: This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. Lessons: The pitfall of misdiagnosing this tumor as DVT is a useful reminder. PMID:29145269

    In a previous study, we described an elevated prevalence of human papillomavirus (HPV) in two specific types of squamous cell carcinoma of the vulva designated basaloid carcinoma (BC) and warty carcinoma (WC) compared with the conventional type of keratinizing squamous cell carcinoma (KSC). To determine whether there were other differences in their clinical presentation or behavior, we examined 100 cases of squamous cell carcinoma of the vulva classified as BC (28 cases), WC (seven cases), and KSC (65 cases). We included only cases in which tissue adjacent to the tumor was present so that the presence of intraepithelial lesions (squamous hyperplasia, lichen sclerosus, and vulvar intraepithelial neoplasia [VIN]) could be correlated with the different types of invasive carcinomas. Microscopically, BC was characterized by a relatively uniform population of small, ovoid cells with a high nuclear-cytoplasmic ratio resembling VIN 3. Although WC was similar to typical squamous cell carcinoma, it contained many squamous cells that displayed marked nuclear pleomorphism, enlargement, atypia, and multinucleation in conjunction with cytoplasmic cavitation resembling koilocytotic atypia in intraepithelial lesions. The majority of the women with BC and WC were less than 60 years of age, and the proportion of black women was higher as compared with the women with KSC, the majority of whom were white and over 65 years of age. On crude comparison, women with BC appeared to have a survival advantage compared with women with KSC; however, through multivariate modelling, when all possible confounding variables were taken into account, there was little residual impression of a survival advantage of women with BC compared with those having KSC. Substantial differences were found among the three types of carcinoma with regard to the prevalence of adjacent intraepithelial lesions. Squamous hyperplasia was found adjacent to KSC in 54 (83%) of the 65 cases, whereas 27 (77%) of 35 cases of

    Sporotrichosis is a subcutaneous mycosis caused by Sporothrix sp., a dimorphic fungus. Although the cutaneous form is the most frequent form, the ocular presentation has been increasingly diagnosed in epidemic areas. We describe three cases of ocular sporotrichosis with the involvement of the ocular adnexa due to autoinoculation without trauma with successful antifungal treatment. Patient 1: A 68-year-old woman presented with granulomatous conjunctivitis of the right eye with an ulcerated nodule on the right temporal region for 5 months. Patient 2: A 46-year-old woman with conjunctival hyperemia of the left eye with associated periorbital edema and erythema for the past 4 months was referred to the Dermatology Department due to an ulcerated nodule on the left malar region. Patient 3: A 14-year-old boy presented to the emergency department with inferior palpebral edema with a 5-day evolution. Specimens were obtained from the lesions of the three patients, and the cultures were positive for Sporothrix sp. The three cases were diagnosed as ocular sporotrichosis and were successfully treated with itraconazole (200-400 mg/d). Two of the three patients developed sequelae such as conjunctival fibrosis and symblepharon. We emphasize the importance of the ophthalmologist being familiar with the diagnosis and management of this rare and frequently misdiagnosed form of sporotrichosis.

The authors retrospectively reviewed patient demographics, serum alkaline phosphatase (AKP) levels, preoperative biopsy pathologic reports, pathologic materials, imaging findings, and treatment outcomes from 26 patients with TOS. Patient images from radiography (26 cases) and magnetic resonance (MR) imaging (22 cases) were evaluated by 3 authors in consensus for intrinsic characteristics. There were 15 male and 11 female patients in the study, with an age of 9-32 years (mean age 15.9 years). Eighteen of 26 patients died of lung metastases within 5 years of follow-up. The distal femur was affected more commonly (14 cases, 53.8%). Regarding serum AKP, normal (8 cases) or mildly elevated (18 cases) levels were found before preoperative chemotherapy. Radiographs showed geographic bone lysis without sclerotic margin (26 cases), cortical destruction (26 cases), periosteal new bone formation (24 cases), soft-tissue mass (23 cases), and matrix mineralization (4 cases). The aggressive radiographic features of TOS simulated the appearance of conventional high-grade intramedullary osteosarcoma, though different from aneurysmal bone cyst. MR images demonstrated multiple big (16 cases) or small (6 cases) cystic spaces, fluid-fluid levels (14 cases), soft-tissue mass (22 cases), and thick peripheral and septal enhancement (22 cases). Nine of 26 cases were misdiagnosed as aneurysmal bone cysts by preoperative core-needle biopsy, owing to the absence of viable high-grade sarcomatous cells in the small tissue samples. The aggressive growth pattern with occasional matrix mineralization, and multiple big or small fluid-filled cavities with thick peripheral, septal, and nodular tissue surrounding the fluid-filled cavities are characteristic imaging features of TOS, and these features are helpful in making the correct

    This report describes a case of first-onset narcolepsy in a six-year-old female that was misdiagnosed as atypical epilepsy and other diagnoses at eight different hospitals over a period of 10 months before the correct diagnosis was made. The diagnosis of narcolepsy is more difficult in children because very few of them experience all four cardinal symptoms of narcolepsy - paroxysmal sleep, cataplexy, hypnagogic hallucination, and sleep paralysis - and they often have a more prolonged onset and diverse symptoms. To decrease the time lag between initial presentation and accurate diagnosis, we recommend that in all cases in which children report excessive sleep of unknown etiology - regardless of the associated symptoms - that sleep monitoring and sleep latency tests be conducted to rule out the possibility of narcolepsy. The case highlights the wide variety of presentations of uncommon psychiatric conditions, particularly in children, and the need for clinicians to be aware of the atypical presentations of these conditions when collecting medical histories.

    PubMed

    Gauthier, Kimberley; Rocheleau, Christian E

    2017-01-01

    Epidermal growth factor receptor (EGFR)-mediated activation of the canonical Ras/MAPK signaling cascade is responsible for cell proliferation and cell growth. This signaling pathway is frequently overactivated in epithelial cancers; therefore, studying regulation of this pathway is crucial not only for our fundamental understanding of cell biology but also for our ability to treat EGFR-related disease. Genetic model organisms such as Caenorhabditis elegans, a hermaphroditic nematode, played a vital role in identifying components of the EGFR/Ras/MAPK pathway and delineating their order of function, and continues to play a role in identifying novel regulators of the pathway. Polarized activation of LET-23, the C. elegans homolog of EGFR, is responsible for induction of the vulval cell fate; perturbations in this signaling pathway produce either a vulvaless or multivulva phenotype. The translucent cuticle of the nematode facilitates in vivo visualization of the receptor, revealing that localization of LET-23 EGFR is tightly regulated and linked to its function. In this chapter, we review the methods used to harness vulva development as a tool for studying EGFR signaling and trafficking in C. elegans.

    Aggressive angiomyxoma (AA) is a distinctive soft tissue tumor with a high risk of local recurrence. Clinicians must be aware of this rare tumor pre-operatively. Excision is the preferred method of AA treatment. The case report presents a case of a 36-year-old woman who was difficulty in walking due to a non-painful tumor in the abdomen and perineum. She was misdiagnosed as abdomen neurofibroma for more than 10 years, and an operation was performed in 1997. However, the tumor was incompletely resected because its huge volume accompanies with extensive infiltration and bleeding. The tumors in her abdomen and perineum were growing gradually, and the latter became a large lump which impeded her daily life. In 2008, the perineal tumor was incompletely resected, which weighed 10725 g. The severe hemorrhage had been ceased by Gonadotropin-Releasing Hormone treatment. She is alive till now. Details of the history and operative procedures are presented. An AA diagnosis was made by microscopy immunohistochemically. Long-time misdiagnosis and improper treatment are the important reasons for making it impossible to be radically resected. Pathological and immunohistochemical examination are important for avoiding misdiagnosis. For this case, there is a remaining tumor in her abdomen. A special project including further follow-up and treatment will be taken out.

    Primary vulvar Ewing sarcoma (ES)/PNET is an uncommonly documented tumor, especially with molecular results. A 10-year-old girl presented with left vulvar swelling, a year ago. Her abdominopelvic ultrasound revealed a 12 cm × 8 cm sized, mixed echogenic blood-filled lesion in the left vulva; radiologically considered as a hematoma. Vulvectomy revealed a multinodular grey-brown tumor, microscopically comprising malignant round cells. Immunohistochemically, tumor cells diffusely expressed MIC2/CD99 and Fli1 and subsequently displayed EWSR1 rearrangement, confirming diagnosis of ES/PNET. Subsequently, PET-CT scan revealed residual local lesion with lung metastases. The patient was induced on EFT 2001 chemotherapy protocol. Three months after chemotherapy completion, there was no metabolically active disease on PET scan. Four months later, MRI disclosed recurrent primary and metastatic pulmonary lesions. She was planned for scar excision and adjuvant radiotherapy, but unfortunately defaulted further treatment. This forms the eighth case of primary vulvar ES/PNET confirmed with molecular cytogenetic result, underscoring therapeutic value of objective diagnosis in such cases.

  16. Case report of narcolepsy in a six-year-old child initially misdiagnosed as atypical epilepsy

    Summary This report describes a case of first-onset narcolepsy in a six-year-old female that was misdiagnosed as atypical epilepsy and other diagnoses at eight different hospitals over a period of 10 months before the correct diagnosis was made. The diagnosis of narcolepsy is more difficult in children because very few of them experience all four cardinal symptoms of narcolepsy – paroxysmal sleep, cataplexy, hypnagogic hallucination, and sleep paralysis – and they often have a more prolonged onset and diverse symptoms. To decrease the time lag between initial presentation and accurate diagnosis, we recommend that in all cases in which children report excessive sleep of unknown etiology – regardless of the associated symptoms – that sleep monitoring and sleep latency tests be conducted to rule out the possibility of narcolepsy. The case highlights the wide variety of presentations of uncommon psychiatric conditions, particularly in children, and the need for clinicians to be aware of the atypical presentations of these conditions when collecting medical histories.

    Misdiagnosis of a urethral foreign body (FB) as urethral stricture leads to inadequate management and prolonged treatment duration. A 55-year-old male patient was referred with complaints of difficulty in voiding and poor urinary stream for 2 months. He initially presented at a primary healthcare centre and was misdiagnosed as urethral stricture and was scheduled for urethroplasty. Surprisingly, intraoperative cystourethroscopy performed by us revealed that the urethra had been obstructed by an FB. The FB was gently pushed into the bladder and retrieved. The postoperative course was uneventful. The present case represents a rare occurrence of polyembolokoilamania or insertion of a FB into any bodily orifice for sexual gratification. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Epstein-Barr virus (EBV)-associated T-cell lymphoproliferative disease (LPD) is not uncommon in China, but gastrointestinal involvement is very rare. We report on an immunocompetent patient with EBV-associated T-cell LPD of the colon. The 26-year-old man was initially misdiagnosed with ulcerative colitis (UC). A colon biopsy revealed the presence of small to medium-sized lymphoid cells infiltrating the intestinal wall. The neoplastic cells expressed CD3, CD5, and granzyme B, not CD56. EBV-encoded small ribonucleic acid was detected in the tumor cells of the colon as well as the lymph node, and the T-cell receptor gene rearrangement result displayed δ gene monoclonal rearrangement. The patient died 2 moths after the diagnosis. The clinical course of EBV-associated T-cell LPD is aggressive and the prognosis is poor, the wrong diagnosis may delay treatment. Therefore, we should be very careful to prevent misdiagnosis. When patients have multiple intestinal ulcers that are not typical of UC and the clinical course is unusual, although morphology looks like inflammatory change, pathologist should consider the possibility of EBV-associated LPD. The treatment strategy and prognosis of these two diseases are different.

  19. H3K9me2/3 Binding of the MBT Domain Protein LIN-61 Is Essential for Caenorhabditis elegans Vulva Development

    2011-01-01

    MBT domain proteins are involved in developmental processes and tumorigenesis. In vitro binding and mutagenesis studies have shown that individual MBT domains within clustered MBT repeat regions bind mono- and dimethylated histone lysine residues with little to no sequence specificity but discriminate against the tri- and unmethylated states. However, the exact function of promiscuous histone methyl-lysine binding in the biology of MBT domain proteins has not been elucidated. Here, we show that the Caenorhabditis elegans four MBT domain protein LIN-61, in contrast to other MBT repeat factors, specifically interacts with histone H3 when methylated on lysine 9, displaying a strong preference for di- and trimethylated states (H3K9me2/3). Although the fourth MBT repeat is implicated in this interaction, H3K9me2/3 binding minimally requires MBT repeats two to four. Further, mutagenesis of residues conserved with other methyl-lysine binding MBT regions in the fourth MBT repeat does not abolish interaction, implicating a distinct binding mode. In vivo, H3K9me2/3 interaction of LIN-61 is required for C. elegans vulva development within the synMuvB pathway. Mutant LIN-61 proteins deficient in H3K9me2/3 binding fail to rescue lin-61 synMuvB function. Also, previously identified point mutant synMuvB alleles are deficient in H3K9me2/3 interaction although these target residues that are outside of the fourth MBT repeat. Interestingly, lin-61 genetically interacts with two other synMuvB genes, hpl-2, an HP1 homologous H3K9me2/3 binding factor, and met-2, a SETDB1 homologous H3K9 methyl transferase (H3K9MT), in determining C. elegans vulva development and fertility. Besides identifying the first sequence specific and di-/trimethylation binding MBT domain protein, our studies imply complex multi-domain regulation of ligand interaction of MBT domains. Our results also introduce a mechanistic link between LIN-61 function and biology, and they establish interplay of the H3K9me2

    2013-05-01

    We present the case of a 23-year-old female with bilateral ectopic breast tissue of the vulva, the repair of which necessitated a novel labiaplasty technique. Labiaplasty is becoming an increasingly frequent cosmetic procedure, and the popularity of brief didactic labiaplasty courses has risen in response to consumer demand. There is a paucity of detailed anatomic description of female sensory innervation patterns to the clitoris and surrounding structures. This places patients at risk for denervation of clitoral structures during labiaplasty procedures. Our novel technique proposes a method of individualized patient neurosensory mapping preoperatively, which allows for surgical planning to avoid injury to the sensory branches of the dorsal clitoral nerve. A 23-year-old female presented with bilateral vulvar masses that involved the clitoral complex, which had first become apparent during the second trimester of pregnancy, and failed to resolve in the postpartum period. We describe the preoperative planning and intraoperative approach and dissection to labiaplasty in this patient, which was complex given the size of the masses, and specifically designed to avoid injury to sensory branches of the dorsal clitoral nerve. As labiaplasty becomes more common, it is important to approach labiaplasty patients with a detailed understanding of the sensory innervation of the clitoris and surrounding structures, to avoid nerve injury and resultant sexual dysfunction. Traditional labiaplasty approaches may violate the sensory innervation patterns of the clitoral region, thus causing a sensory loss that affects patient sexual function. Our novel approach to preoperative clitoral nerve sensory mapping provides an alternative method of labiaplasty that may avoid denervation injury.

    This case report describes a complex radical 3D-Conformal Radiotherapy treatment planning, dosimetric issues and outcome of definitive treatment of un-resectable carcinoma of the vulvar in a 42-year old lady. The patient presented with large fungating mass of the vulva which was biopsy confirmed as Keratinizing Squamous Cell Carcinoma. Further staging investigation revealed locally advanced disease (T4), with bilateral inguinal lymph nodes involvement. There is no systemic metastasis or intra-pelvic nodes. The patient was seen by Gynae-Oncology team and the disease was deemed un-resectable without significant morbidity. She was treated to a total dose of 64.8Gy in 36 fractions over 7 weeks with concurrent weekly Cisplatinum in 2 phases. 3D-Conformal radiotherapy technique using the modified segmental boost technique (MSBT, large PA and small AP photon fields with inguinal electron matching) was used. TLD chips were used for in-vivo dose verification in phase 1 and 2 of the treatment. At completion of planned radiotherapy, patient had a complete clinical response, grade 2-3 skin toxicity, grade 2 rectal toxicity, and grade 2 dysuria Vulval Squamous Cell Carcinomas are very radiosensitive tumours and the skills of the treating Radiation Oncologist, Dosimetrists, Physicist, Radiation Therapist and also nurses is of foremost importance is ensuring good clinical outcomes.

    Human Schistosoma haematobium infection that causes urinary schistosomiasis occurs in Africa and the eastern Mediterranean, and China is only endemic for S. japonicum. In this report, we reported an imported case with S. haematobium infection returning from Angola to Shaanxi Province, northwestern China, where S. japonicum is not endemic. The case was misdiagnosed as ureteral calculus, invasive urothelial carcinoma and eosinophilic cystitis in several hospitals, and was finally diagnosed by means of serological assay followed by microscopic examination of the urine sediment. The patient was then treated with praziquantel, and a satisfactory outcome was obtained. As S. haematobium is not indigenous to China, most Chinese doctors and medical technicians are unfamiliar with this introduced parasitic disease, therefore, they need to increase the awareness of its existence when they encounter persons who have visited or resided in endemic areas, and the techniques for detection of the parasite, so as to reduce the misdiagnosis. In addition, health education should be given to those who will go to the endemic areas to improve their knowledge and awareness on prevention and control of schistosomiasis haematobia, thereby reducing the risk of exposure to the infested freshwater.

    Differentiating salient histopathologic changes from normal anatomic features or tissue artifacts can be decidedly challenging, especially for the novice fish pathologist. As a consequence, findings of questionable accuracy may be reported inadvertently, and the potential negative impacts of publishing inaccurate histopathologic interpretations are not always fully appreciated. The objectives of this article are to illustrate a number of specific morphologic findings in commonly examined fish tissues (e.g., gills, liver, kidney, and gonads) that are frequently either misdiagnosed or underdiagnosed, and to address related issues involving the interpretation of histopathologic data. To enhance the utility of this article as a guide, photomicrographs of normal and abnormal specimens are presented. General recommendations for generating and publishing results from histopathology studies are additionally provided. It is hoped that the furnished information will be a useful resource for manuscript generation, by helping authors, reviewers, and readers to critically assess fish histopathologic data.

    Blunt injuries to the chest wall are an important chapter on emergency room (ER) departments, being the third most common injuries in trauma patients which ominous complications could appear. This article describes different types of traumatic events affecting the chest wall, which maybe misdiagnosed with conventional X-ray. Special emphasis has been done in computed tomography (CT) and multidetector CT (MDCT) imaging. This technique is considered the “gold-standard” for those traumatic patients, due to its fast acquisition covering the whole area of interest in axial plane, reconstructing multiplanar (2D, 3D) volume-rendered images with a superb quality and angiographic CT capabilities for evaluating vascular damage. Complementary techniques such as ultrasonography (US) and magnetic resonance imaging (MRI) may improve the diagnostic accuracy due to its great capacity in visualising soft-tissue trauma (muscle-tendinous tears) and subtle fractures. All these imaging methods have an important role in quantifying the severity of chest wall trauma. The findings of this study have been exposed with cases of our archives in a didactic way.

    Post-infectious organizing pneumonia (OP) is a rare clinical entity associated with nonspecific clinical features and can be easily misdiagnosed. This study aimed to investigate the clinical feature differences between cryptogenic organizing pneumonia (COP) and post-infectious OP. We retrospectively analyzed clinical data on demographic characteristics, clinical manifestations, laboratory findings, radiological findings, treatments, outcomes, and prognosis of 31 cases of COP and 26 cases of post-infectious OP. Patients were treated in Beijing Chao-yang Hospital between July 2005 and January 2013. Compared with patients with COP, patients with post-infectious OP are more prone to show fever (88.5% vs. 38.7%, p < 0.05) and crackles (46.2% vs. 6.5%, p < 0.05). The elevation of PCT serum levels is more obvious in the early stage of post-infectious OP (5.24 ± 1.96 vs. 0.28 ± 0.09) and bilateral lung consolidations and patchy shadows are the most common radiological findings (70.2%). Pathogens are more prone to be confirmed within 48 hours after admission and the diagnosis time is longer (10.0 ± 0.8 vs. 7.2 ± 0.4 days). The incidence of mechanical ventilation (50% vs. 19.4%) and the utilization rate of antibiotics are higher (100.0% vs. 70.9%). The dosage (0.58 ± 0.04 vs. 0.78 ± 0.04 mg) and utilization time of glucocorticoids (5.7 ± 0.4 vs. 7.9 ± 0.8 months) are obviously reduced. The morbidity of post-infectious OP is not uncommon. PCT serum level is helpful in the diagnosis and differential diagnosis, but invasive procedures like bronchoscopic or surgical lung biopsy are the golden-standard methods to confirm diagnosis. Similar to COP, antibiotics are effective in the early stage of post-infectious OP, but glucocorticoids are effective in the late stage. The prognosis of post-infectious OP is good.

    Urea cycle disorders are a group of inborn errors of metabolism caused by dysfunction of any of the six enzymes or two transport proteins involved in urea biosynthesis. In this paper, we report a patient who presented with neurological dysfunction and coma in the immediate postpartum period. She was misdiagnosed for many years as a case of multiple sclerosis. The importance of reporting this case is to illustrate that the wrong diagnosis of patients as being affected with multiple sclerosis for many years due to magnetic resonance imaging abnormalities rather than the classic relapsing-remitting nature of the disease may lead to catastrophic consequences. The patient was treated with intravenous steroids several times, which is contraindicated in patients with urea cycle disorders as it may precipitate acute hyperammonemic attacks. In addition, the management of urea cycle disorder could have started earlier and avoided multiple admissions to the intensive care unit. We believe that the presence of symmetric hyperintense insular cortical changes are seen in multiple hyperammonemic processes, and in the context of the clinical presentation and high ammonia levels can be suggestive of a urea cycle disorder. For any patient presenting with atypical clinical features, images should be reviewed and discussed in detail with an experienced neuroradiologist. In addition, the ammonia levels should be checked if a urea cycle disorder is suspected.

    Examine women's perceptions of what is 'normal' and 'desirable' in female genital appearance. Experiment with random allocation across three conditions. Community. A total of 97 women aged 18-30 years. Women were randomly assigned to view a series of images of (1) surgically modified vulvas or (2) nonmodified vulvas, or (3) no images. They then viewed and rated ten target images of surgically modified vulvas and ten of unmodified vulvas. Women used a four-point Likert scale ('strongly agree' to 'strongly disagree'), to rate each target image for 'looks normal' and 'represents society's ideal'. For each woman, we created two summary scores that represented the extent to which she rated the unmodified vulvas as more 'normal' and more 'society's ideal' than the modified vulvas. For ratings of 'normality,' there was a significant effect for condition (F2,94  = 2.75 P = 0.007, radj2 = 0.082): women who had first viewed the modified images rated the modified target vulvas as more normal than the nonmodified vulvas, significantly different from the control group, who rated them as less normal. For ratings of 'society's ideal', there was again a significant effect for condition (F2,92  = 7.72, P < 0.001, radj2 = 0.125); all three groups rated modified target vulvas as more like society's ideal than the nonmodified target vulvas, with the effect significantly strongest for the women who had viewed the modified images. Exposure to images of modified vulvas may change women's perceptions of what is normal and desirable. This may explain why some healthy women seek labiaplasty. © 2013 Royal College of Obstetricians and Gynaecologists.

    We analyzed parasitic diseases diagnosed by tissue biopsy specimens at KyungHee Medical Center (KMC) from 1984 to 2005. The total number of parasite infection cases was 150 (0.07%) out of the total 211,859 biopsy specimens submitted for histopathological examinations. They consisted of 62 cysticercosis, 23 sparganosis, 16 paragonimiasis, 15 amebiasis, 11 anisakiasis, 11 clonorchiasis, 3 ascariasis, 2 scabies, 2 enterobiasis, 2 trichuriasis, 1 leishmaniasis, 1 taeniasis, and 1 thelaziasis. Out of 62 cysticercosis cases, 55 were detected in subcutaneous tissues or the central nerve system. Eighteen out of 23 sparganosis cases were involved in muscular and subcutaneous tissues. In most anisakiasis cases, the involved organ was the stomach. The lung and the pleura were the most common site of paragonimiasis. The incidence of parasitic diseases during the first 5 years (1984-1988) was the highest of all observed periods. After 1989, similar incidences were shown throughout the period. Whereas cysticercosis was diagnosed in 34 cases during 1984-1988, no case has been diagnosed since 2000. In the case of sparganosis, the chronological incidence was almost uniform throughout the period 1984-2005. Paragonimiasis showed a similar tendency to cysticercosis. In gender and age distribution of parasitic diseases, men showed higher incidence rates than females, and the age groups of the 40s or older indicated higher infection frequencies than other age groups. Therefore, these results are a significant report to appear the tendency of human parasitic disease diagnosed by tissue biopsy in association with parasitosis at KMC in Seoul. PMID:20333293

    The objective of the study was to determine whether reproductive-age women are more likely to perceive their vulva as abnormal compared with older-aged women. Women aged 18-44 years (group 1) and 45-72 years (group 2) completed a survey on demographics, grooming patterns, vulvar perceptions, and source of information about the vulva. There was no difference between group 1 and group 2 in how often women looked at their vulva or their perception of having a normal vulva (91% vs 93%, P = .76). Both groups were satisfied with the appearance of their vulva (81% vs 82%, P = .71). A higher percentage in group 2 would consider cosmetic surgery if cost were not an issue versus group 1 (15% vs 8%, P = .05). A woman's age does not have an impact on her perception of a normal vulva. The majority of women perceived their vulva to be normal and were satisfied with its appearance. However, older women are more interested in cosmetic vulvar surgery. Copyright © 2012 Mosby, Inc. All rights reserved.

  10. Unusual mucoepidermoid carcinoma of the liver misdiagnosed as squamous cell carcinoma by intraoperative histological examination

    PubMed Central

    2014-01-01

    As rare condition, mucoepidermoid carcinoma may occur in liver although its etiology and pathogenesis is still unclear. We report here a case of intrahepatic mucoepidermoid carcinoma misdiagnosed as cholangiocarcinoma and squamous cell carcinoma by preoperative radiologic and intraoperative histological examinations, respectively. A 60-year-old woman presented with a 1-month history of progressive jaundice, epigastric discomfort, and weight loss with slightly increased carbohydrate antigen 19-9 (CA19-9). Computed tomography (CT) showed a large tumor, 8.0 cm in diameter, in the left lobe of the liver. A preliminary diagnosis of a cholangiocarcinoma of the liver was made. In the intraoperative histological examination, a diagnosis of squamous cell carcinoma was made based on predominantly invasive epidermoid cells with abundant keratinization and absence of mucin-producing cell component. However, postoperative histological diagnosis of the lesion was mucoepidermiod carcinoma of liver by thoroughly microscopical inspection and the presence of mucin-producing cells confirmed by Alcian blue staining. Despite surgical excision and chemotherapy, the tumor showed very aggressive malignancy with tumor recurrence. The patient died shortly afterward, surviving 6 months after surgery. Due to its rarity and distinct morphological features, mucoepidermoid carcinoma might be erroneously interpreted as squamous cell carcinoma by those who were not familiar with this condition in unusual locations. Therefore, removal of sufficient tissue from different portions of the lesion is essential for the surgeons and pathologists to make a precise diagnosis in the intraoperative histological examination.

    Many waterborne helminthes are opportunistic parasites that can travel directly from animals to man and may contain forms capable of penetrating the skin. Among these, Sparganum is the pseudophyllidean tapeworm that belongs to the genus Spirometra, which is responsible for parasitic zoonosis; it is rarely detected in Europe and is caused by the plerocercoid infective larva. Thus far, only six cases of cutaneous and ocular sparganosis have been reported in Europe; two and four cases have occurred in France and Italy, respectively. Herein, we describe a new case of sparganosis in Italy that affected a male diver who presented to the Bambino Gesù Children’s Hospital of Rome. The patient’s skin biopsy was submitted to the Parasitology department who, in consultation with Pathology, concluded that the morphologic and microscopic findings were those of Sparganum spp. larvae. The patient recovered following a single dose of 600 mg praziquantel. PMID:26751512

    Children commonly undergo vesicograms for diagnosing vesicoureteral reflux (VUR). This requires urethral catheterization with transurethral replacement. We report misdiagnosed or related complications due to indwelling urethral catheters unintentionally placed in the ureter. From our computerized urology records over an 18-year period from January 1995 to May 2013, we retrospectively identified nine cases of 1850 vesicograms that had misdirection of a urethral catheter placed in a ureter. Foley catheters with inflating balloons were used to obtain the vesicograms. In all, 1850 vesicograms were performed (746 males, 1104 females; age 1 week to 14 years, mean age 3.8 years) using standard radiological techniques. Size 6-10 Fr indwelling urethral catheters were used, depending on the patient's age and gender. In nine cases (five females, four males), a misdirected urethral catheter was discovered in one of the ureters. The urethral catheter was in the left ureter in four patients and in the right ureter in five patients. Cystoscopic examination found ectopic ureteral openings in six patients: at the bladder neck in four and just below the bladder trigone in two. Three patients in this group with ectopic ureters were followed due a misdiagnosis of VUR. The remaining three patients had grade 3 or 4 VUR. In this group, the catheter passed into the ureter because of the enlarged ureterovesical junction. In one patient with VUR, intraparenchymal fluid leakage and transient hematuria occurred due to the rapid tension increase following the fast injection of contrast with liquid to one ureter. Although placing an indwelling urethral catheter is a relatively safe procedure, complications can occur, particularly in patients with ureterovesical anomalies, such as high-grade VUR or an ectopic ureter. Using catheters with inflating balloons can cause rapid increases in tension in the ureter, and related complications.

    Human Papillomaviruses (HPVs) are involved in the etiology of anogenital and head and neck cancers. The HPV DNA prevalence greatly differs by anatomical site. Indeed, the high rates of viral DNA prevalence in anal and cervical carcinomas contrast with the lower fraction of cancer cases attributable to HPVs in other anatomical sites, chiefly the vulva, the penis and head and neck. Here we analyzed 2635 Formalin Fixed Paraffin Embedded surgical samples that had previously tested negative for the presence of HPVs DNA using the SPF10/DEIA procedure, in order to identify the presence of other PVs not explicitly targeted by standard molecular epidemiologic approaches. All samples were reanalyzed using five broad-PV PCR primer sets (CP1/2, FAP6064/FAP64, SKF/SKR, MY9/MY11, MFI/MFII) targeting the main PV main clades. In head and neck carcinoma samples (n=1141), we recovered DNA from two BetaHPVs, namely HPV20 and HPV21, and from three cutaneous AlphaPVs, namely HPV2, HPV57 and HPV61. In vulvar squamous cell carcinoma samples (n=902), we found one of the samples containing DNA of one cutaneous HPV, namely HPV2, and 29 samples contained DNA from essentially mucosal HPVs. In penile squamous cell carcinoma samples (n=592), we retrieved the DNA of HPV16 in 16 samples. Our results show first that the SPF10/DEIA is very sensitive, as we recovered only 2.1% (55/2635) false negative results; second, that although the DNA of cutaneous HPVs can be detected in cancer samples, their relative contribution remains anyway minor (0.23%; 6/2635) and may be neglected for screening and vaccination purposes; and third, their contribution to malignancy is not necessarily warranted and needs to be elucidated.

  14. Significance of Serology by Multi-Antigen ELISA for Tissue Helminthiases in Korea

    PubMed Central

    2017-01-01

    It is clinically important to differentiate tissue-invading helminthiasis. The purpose of this study was to assess the specific immunoglobulin G (IgG) antibody positive rates for clonorchiasis, paragonimiasis, cysticercosis, and sparganosis 4 helminthiases from 1996 to 2006 using multi-antigen enzyme-linked immunosorbent assay (ELISA) in Korea. Results of 6,017 samples, which were referred to our institute for serodiagnosis, were analyzed. The subjects with positive serum IgG antibodies were 1,502 (25.0%) for any of the 4 helminthiases. The overall positive numbers for clonorchiasis, paragonimiasis, cysticercosis, and sparganosis were 728 (12.1%), 166 (2.8%), 729 (12.1%), and 263 (4.4%), respectively. The positive serologic reaction to multi-antigens was determined in 309 (20.6%) of the 1,502 total seropositive subjects. Those with multi-antigen positivity were regarded as positive for the antigen of strongest reaction but cross-reaction to others with weak positive reaction. Annual seropositive rates for those 4 tissue helminthiases ranged from 12.1% to 35.7%. The highest rate was observed in age from 60 to 69 years old and prevalence of men (27.4%; 1,030/3,763) was significantly higher than of women (19.1%; 332/1,741). Hospital records of 165 ELISA positive patients were reviewed to confirm correlation with their clinical diagnosis. Paragonimiasis was highly correlated as 81.8% (9/11), cysticercosis 29.9% (20/67), clonorchiasis 29.0% (20/69), and sparganosis 11.1% (2/18). In conclusion, the multi-antigen ELISA using 4 helminth antigens is useful to differentiate suspected tissue-invading helminthiases, especially ELISA diagnosis of paragonimiasis is reliable. The seropositivity is still high among suspected patients in Korea. PMID:28581268

    The therapeutic outcomes of patients with advanced vulvar cancer are poor. Multi-modality treatments including concurrent chemoradiation or different regimens of neoadjuvant chemotherapy (NACT), and surgery have been explored to reduce the extent of surgery and morbidity. The present single-institution trial aimed to evaluate the efficacy and toxicity of paclitaxel and cisplatin in locally advanced vulvar cancer. From 2002 to 2009, 10 patients with stage III-IV locally advanced squamous cell carcinoma of the vulva were prospectively treated with 3 courses of paclitaxel-ifosfamide-cisplatin or paclitaxel-cisplatin. Nine of them subsequently underwent radical local excision or radical partial vulvectomy and bilateral inguino-femoral lymphadenectomy. The clinical response rate of all enrolled patients was 80%, whereas the pathological responses included 1 case with complete remission, 2 with persistent carcinoma in situ, and 6 invasive cancer cases with tumor shrinkage of more than 50%. Four patients had positive nodes. Forty percent of patients experienced grade 3-4 bone marrow toxicity, which was successfully managed with granulocyte-colony stimulating factor, even in cases of elderly patients. Median progression-free survival after surgery was 14 months (range, 5 to 44 months). Six of the 7 recurrent cases were local, and 3 of them were treated with salvage surgery while the other 3 received radiation with or without chemotherapy. After a median follow-up period of 40 months (range, 5 to 112 months), 55.5% of patients remained alive with no evidence of disease, including 2 long-term survivors after recurrence at 5 and 9 years. Based on the high response rate and manageable toxicity, NACT with paclitaxel and cisplatin with or without ifosfamide followed by surgery could be considered as a therapeutic option for locally advanced vulvar cancer.

    Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited syndrome occurring in one out of 36,000 live births. Diagnosis could be a challenge in patients with no familial VHL history. Renal cancer (RCC) represents one of the most important manifestations. RCC is usually recurrent and multifocal. Actually treating RCC in VHL patients represent a clinical dilemma: the oncological outcomes must be balanced against renal function preservation. A young man with a negative familial history was referred to our department with seven misdiagnosed renal masses. VHL disease was determined through genetic test. The multiple RCCs were treated by surgery and percutaneous thermal ablation by radiofrequency ablation (RFA) with complete control of RCC and no impairment of renal function. This case history confirms that VHL disease has to be suspected in young patients with evidence of synchronous multiple renal masses and in presence of specific clinical criteria.RFA appears to be safe in terms of oncological radicalism and in renal function preservation.In hereditary RCC, we should purpose, whenever it is possible, minimally invasive treatment in terms of low hospital stay and a minimal loss of renal tissue.

    Methemoglobinemia is a rare overlooked differential diagnosis in patients presented with cyanosis and dyspnea unrelated to cardiopulmonary causes. Our patient is 29 year old Indian non-smoker male, his story started 6 months prior to presentation to our center when he had generalized fatigue and discoloration of hands. He presented with persistent polycythemia with elevated hemoglobin level. The patient was misdiagnosed in another center as polycythemia and treated with Imatinib. The diagnosis of PV was revisited and ruled out in view of negative JAK2, normal erythropoietin level and absence of features of panmyelosis. Clinical cyanosis and lowoxygen saturation in the presence of normal arterial oxygen tension was highly suggestive of methemoglobinemia. Arterial blood gas revealed a methemoglobin level of 38% (normal: 0-1.5%). Cytochrome B5 reductase (Methemoglobin reductase B) was deficient at level of <2.6 U/g Hb) (normal: 6.6-13.3), consistent with methemoglobin reductase (cytochrome b5) deficiency and hence the diagnosis of congenital methemoglobinemia was established. The role of Imatinib in provoking methemoglobinemia is questionable and association between Imatinib and methemoglobinemia never described before. In our case, there were no other offending drugs in aggravating the patients' symptoms and cyanosis. The patient started on Vitamin C 500 mg once daily for which he responded well with less cyanosis and significant reduction of methemoglobin level. Congenital methemoglobinemia is a rare underreported hemoglobin disease and often clinically missed. Upon extensive review of English literature for cases of congenital methemoglobinemia due to deficiency of cytochrome b5 reductase, we found 23 cases diagnosed as type I (including the case reported here). 17 cases (~74%) of type I and 6 cases (27%) of type II. There is male predominance 73% versus 26% in females. Almost half of reported cases 12 cases (52%) are Indian, 2 Japanese, 3 English, 2 Arabic, one

    Since the advent of computed tomography and magnetic resonance imaging scans, neurological disorders have less often been falsely labeled as conversion disorder (CD). However, misdiagnosis of a neurological disorder as CD still occurs, especially in cases with insidious onset. Misinterpretation of la belle indifférence may contribute to such misdiagnosis. Here, we describe a case of progressive supranuclear palsy/Richardson's syndrome (PSPS) misdiagnosed as a case of CD. A 62-year-old woman consulted two different neurologists in 2012 because of falling spells since 2009 and was diagnosed with CD. She was referred to the Clinical Center of Excellence for Body, Mind, and Health for treatment of CD. After neurological examination, blood tests, and psychiatric examination, in which la belle indifférence and a history of incest were found, CD was confirmed. However, despite treatment for CD, the patient's physical symptoms deteriorated over a year. After repeated physical and psychiatric examinations, neurocognitive assessment, and consultation with a third neurologist because of suspicion of neurological disease, the patient was diagnosed with PSPS. La belle indifférence may be a psychological sign in the context of CD, but it may also be an expression of lack of mimic due to Parkinsonism or of eye movement disorder in the context of neurological illness. A diagnosis of CD should not be considered definitive if no improvement occurs in terms of physical, mental, and cognitive symptoms despite appropriate therapy. In case of deterioration, neurological reexamination and reinterpretation of la belle indifférence should be considered.

    Human papillomavirus (HPV) infections may result in benign hyperplasia, caused by low-risk HPV types, or (pre)malignant lesions caused by high-risk HPV types. The molecular basis of this difference in malignant potential is not completely understood. Here, we performed gene profiling of different HPV infected vulvar tissues (condylomata acuminata (n = 5), usual type vulvar intraepithelial neoplasia (uVIN) (n = 9)) and control samples (n = 14) using Affymetrix Human U133A plus 2 GeneChips. Data were analyzed using OmniViz®, Partek® and Ingenuity® Software. Results were validated by real-time RT-PCR and immunostaining. Although similarities were observed between gene expression profiles of low- and high-risk HPV infected tissues (e.g., absence of estrogen receptor in condylomata and uVIN), high-risk HPV infected tissues showed more proliferation and displayed more DNA damage than tissues infected with low-risk HPV. These observations were confirmed by differential regulation of cell cycle checkpoints and by increased expression of DNA damage-biomarkers p53 and γH2AX. Furthermore, FANCA, FANCD2, BRCA1 and RAD51, key players in the DNA damage response, were significantly upregulated (p < 0.05). In addition, we compared our results with publicly available gene expression profiles of various other HPV-induced cancers (vulva, cervix and head-and-neck). This showed p16(INK4a) was the most significant marker to detect a high-risk HPV infection, but no other markers could be found. In conclusion, this study provides insight into the molecular basis of low- and high-risk HPV infections and indicates two main pathways (cell cycle and DNA damage response) that are much stronger affected by high-risk HPV as compared to low-risk HPV.

    To investigate the activity of 5% Imiquimod cream in the primary treatment of vulva intraepithelial neoplasia (VIN) grade 2/3. Patients with histologically confirmed VIN 2/3 were recruited from regional colposcopy units. A Simon two-stage phase 2 study design was used. Imiquimod cream was applied over the abnormal VIN areas by the patients, using an escalating dose regimen for a total treatment duration of 16 weeks. Colposcopy assessments were performed every 2 weeks to evaluate for response. A historical cohort of VIN 2/3 patients treated with primary surgical ablation was used to compare recurrence patterns. Thirty-nine patients enrolled in the study. Six patients dropped out due to side effects and non-compliance with study protocol. Thirty-six patients (92%) had VIN 3. Therapy was well tolerated with the most common observed side effects being only minor skin irritation at the application site. Histologic complete response was observed in 21 patients with partial response in another nine patients. The overall response rate was 77% using intention to treat principle. No VIN progression or cancer was diagnosed. At a median follow-up of 16 months in the whole study cohort, eight recurrences (20.5%) were observed. In comparison, the recurrence rate for primary surgically treated patients was 53.5% (p=0.013). Imiquimod cream was well tolerated and resulted in the regression in a majority of high-grade VIN lesions. The recurrence rate appeared to be comparable to primary surgical ablation.

    There are recent experimental reports on the cross-regulation between molecules involved in the control of the cell cycle and the differentiation of the vulval precursor cells (VPCs) of Caenorhabditis elegans. Such discoveries provide novel clues on how the molecular mechanisms involved in the cell cycle and cell differentiation processes are coordinated during vulval development. Dynamic computational models are helpful to understand the integrated regulatory mechanisms affecting these cellular processes. Here we propose a simplified model of the regulatory network that includes sufficient molecules involved in the control of both the cell cycle and cell differentiation in the C. elegans vulva to recover their dynamic behavior. We first infer both the topology and the update rules of the cell cycle module from an expected time series. Next, we use a symbolic algorithmic approach to find which interactions must be included in the regulatory network. Finally, we use a continuous-time version of the update rules for the cell cycle module to validate the cyclic behavior of the network, as well as to rule out the presence of potential artifacts due to the synchronous updating of the discrete model. We analyze the dynamical behavior of the model for the wild type and several mutants, finding that most of the results are consistent with published experimental results. Our model shows that the regulation of Notch signaling by the cell cycle preserves the potential of the VPCs and the three vulval fates to differentiate and de-differentiate, allowing them to remain completely responsive to the concentration of LIN-3 and lateral signal in the extracellular microenvironment.

    In this study, we aimed to explore the associations between HLA-A\\B\\DRB1 polymorphisms and the risks of vulvar lichen sclerosus (VLS) or squamous cell hyperplasia of the vulva (SCHV) in Han Chinese women. We enrolled 76 Han Chinese women with VLS (Group A), 74 with SCHV (Group B), and 66 healthy women (control group) in this study. Polymerase chain reaction amplification with sequence specific primers (PCR-SSP) was used to determine HLA-A\\B\\DRB1 polymorphisms. Compared with the control group, HLA-A*11, -B*15, and -DRB1*12 were present at a higher frequency in groups A and B, while HLA-B*13 was present at a higher frequency in group A. Fewer women in group A carried HLA-A*31, -DRB1*01, and -DRB1*03 genotypes and fewer women in group B carried HLA-B*40 and -DRB1*03 genotypes. Significant differences were found between group B and the control group for HLA-A*11, -B*15, -B*40, and -DRB1*03, and between group A and the control group for HLA-B*15 and -DRB1*12. The HLA-A*11, HLA-B*13, HLA-B*15, and HLA-DRB1*12 genotypes were associated with a higher risk of VLS, while the HLA-A*31, HLA-DRB1*01, and HLA-DRB1*03 genotypes were associated with a lower risk of VLS. In addition, carrying HLA-A*11, HLA-B*15, HLA-B*35, and HLA-DRB1*12 genotypes, and carrying HLA-B*40 and HLA-DRB1*03 genotypes were found to be risk or protective factors for SCHV, respectively.

    A total of 158 women who either HIV-infected or under iatrogenic immunosuppression were examined regularly during a 4-year period to evaluate if certain vulvar neoplasms and cervical neoplasia have similar associated risk factors. Patients with CIN were matched prospectively with immunocompetent controls with CIN. Forty-eight cervical lesions were detected among patients, including 2 invasive carcinoma and 15 CIN-3 lesions, compared to 11 vulvar lesions, including 2 invasive carcinoma and 7 VIN-3 lesions. Women who have more than five life-time partners were more likely to have HPV-DNA positive cervical swabs and vulvar scrapes as well as cervical and/or vulvar neoplasia. Compared to 2.7% of controls 15.2% of patients with CIN had coexisting high-grade lesions of the vulva. With 1 exception all patients with vulvar neoplasia either suffered from symptomatic immunodeficiency or received immunosuppressive drugs for more than 10 years. Except for 1 VIN-3 lesions, all vulvar neoplasms were associated with HPV-DNA types 16, 31, and/or 33. Six of nine patients as well as the 2 controls with coexisting vulvar and cervical neoplasia had the same HPV-type associated with both lesions. All vulvar lesions were classified as either "warty" or "basaloid". In conclusion cervical and bowenoid/basaloid vulvar neoplasia seem to have a similar HPV-related genesis. Malfunction of the cellular immune response appears to be a cofactor in the genesis of HPV-associated neoplasia at both sites.

The predominant type of carcinoma was squamous cell carcinoma with the lesion originating from the labia. Metastases were found in eight patients. The value of lymphography in the management of carcinoma of the vulva is discussed. The 5 year survival rate was 24%. In the group of patients receiving radiotherapy alone, a high incidence of recurrence was observed. Following adequate surgery for carcinoma ofmore » the vulva, the incidence of recurrence was low. It is concluded that a mature carcinoma of the vulva cannot be cured by radiotherapy as the only modality. (auth)« less

    The ability to vaporize extremely thin layers of epithelial tissue without any char and with minimal thermal necrosis is extremely advantageous in the treatment of superficial lesions of the external genitalia. We present a novel CO2 laser `SwiftLase' flashscan technology capable of providing char free ablation of 3 mm diameter lesions with only 150 micron residual thermal necrosis depth at power level as low as 10 watts. These power levels are achievable with a small transportable CO2 laser. The SwiftLaser is a miniature opto- mechanical scanner which homogeneously covers a 3 mm diameter surface with a 0.1 mm spot size focused beam within 0.1 seconds. The instantaneous beam's dwelling time is 1 millisecond. The instantaneous power density level at the focal point is higher than the threshold for char free ablation, thus providing a large char free ablation crater. Since depth of each ablated layer is 0.1 mm, the depth of treatment can be precisely controlled. The SwiftLaser technology has extensively and successfully been used in the last two years for the treatment of HPV in female lower tracts (Vulvectomy). The same technique may be performed with extramammary Paget's disease of the vulva, penile condylomata, and other epithelial disorders of the external genitalia without damage to surrounding healthy tissue. Technique and clinical results will be discussed.

    Purpose To present the clinical, imaging, pathological and immunohistochemical features of giant cell angiofibroma (GCA). Case presentation In this paper we report an atypical case of a GCA extending from the parotid to the parapharyngeal space. The lesion was being treated as a vascular malformation for one year prior to surgical removal. We summarize the clinical manifestations, imaging, pathological and molecular features of this rare disease. After complete surgical removal of the tumor, immunohistochemical analysis revealed strong positivity for the mesenchymal markers vimentin, CD34, CD31 and CD99 in neoplastic cells. Tumor proliferation antigen marker Ki67 was partly positive (<5% of cells). Tumor cells were negative for muscle-specific actin, epithelial membrane antigen, smooth muscle actin, cytokeratin pan, S100, desmin, glial fibrillary acidic protein, myogenin, MyoD1 and F8. The morphological and immunohistochemical profile was consistent with the diagnosis of GCA. Conclusion GCA is a rare soft tissue tumor that can easily be misdiagnosed in the clinical preoperative setting. In view of the clinical, pathological and molecular features of the tumor, complete surgical removal is the current optimal treatment option, providing accurate diagnosis and low to minimal recurrence rate.

    Through an epidemiological review on the zoonotic tapeworms in Korea, the frequency and severity of the zoonoses have been recognized. Taeniasis and human cysticercosis are of importance to the public health in Korea. The frequency of taeniasis is 0.3% to 12.7% discovered by stool examination and 4.5% to 38.0% discovered by questionaire survey. Taeniasis occurs more frequently in males than in females and, especially, in both sexes in the age-group of 20 to 49. T. saginata is more common that T. solium. No case of human cysticercosis caused by T.saginata has been reported in Korea. To the contrary, human cysticercosis caused by T. solium has been reported frequently during the 1960's. The severity of human cysticercosis is a significant problem of public health in Korea. Old data on bovine cysticercosis in the 1920's and 1930's are not useful for present control measures. Systematic surveys on bovine and swine cysticercosis as well as taeniasis and human cysticercosis are needed in Korea. Cases of sparganosis have been reported frequently during the past 15 years. Most of the 34 cases of sparganosis reported involved the eating of raw snakes and frogs. Most of the cases occurred in older males. Sparganosis in snakes, frogs, chickens, and swine has been reported in Korea. Human infection of Hymenolepis nana ranged from 0.2% to 1.4% discovered by stool examination. A few cases of adult worm collections of Diphyllobothrium latum and Hymenolepis diminuta have been reported in Korea. Two cases of human hydatid disease have been reported in Korea. No study on the disease in domestic animals is available. No case of human infection with dog tapeworm has been reported, even though it is highly prevalent in the indigenous dogs in Korea. I recommend that further study on the zoonotic tapeworms be conducted epidemiologically in Korea to get basic data for the public health programming.

    Introduction. Vulvar cyst in adolescent girls is very uncommon. Epidermoid cyst can be seen in many sites including face, trunk, and extremities but its occurrence in vulva is uncommon. This is the first case of epidermoid cyst of vulva reported in an adolescent girl. Case. A 17-year-old, adolescent girl admitted to our gynecology outpatient clinic with a complaint of painful and palpable mass in her vulva. On examination, a giant mass located in left vulva and labia majora with 11 cm in diameter was seen. The magnetic resonance imaging (MRI) showed a well-defined cystic mass without contrast enhancement. The surgery was advised to the patient and the pathologic examination of mass revealed vulvar epidermoid cyst. Discussion. Vulvar cysts generally grow slowly and the main etiologies are vulvar trauma and surgical interventions including episiotomy and female circumcision in some culture. The exact treatment is total surgical excision and pathologic examination. MRI is an important imaging modality for detection of extension to deep perineal tissue and localization of mass in vulva especially in giant ones. Conclusion. Although vulvar mass in adolescents is rare, the epidermoid cyst with benign origin should be kept in mind. PMID:25949839

    Tuberculosis of the vulva is very rare. It is found in about 0.2% of the cases of genital tract tuberculosis. It usually presents as small shallow ulcers and multiple sinus tracts or rarely as elephantiasis of vulva. Except for very rare cases of primary tuberculosis in the vulva, it is usually associated with tuberculosis elsewhere in the body leading to secondary tuberculosis. Here, we report a case of secondary vulval tuberculosis which presented as a vulval mass in a 40-year-old female patient. The rarity of this presentation in the female genital tract is emphasized.

    Sparganosis is a zoonotic disease caused by the spargana of Spirometra, and snake is one of the important intermediate hosts of spargana. In some areas of China, snake is regarded as popular delicious food, and such a food habit potentially increases the prevalence of human sparganosis. To understand the prevalence of Spirometra in snakes in food markets, we conducted a study in two representative cities (Guangzhou and Shenzhen), during January-August 2013. A total of 456 snakes of 13 species were examined and 251 individuals of 10 species were infected by Spirometra, accounting for 55.0% of the total samples. The worm burden per infected snake ranged from 1 to 213, and the prevalence in the 13 species was 0∼96.2%. More than half (58.1%) of the spargana were located in muscular tissue, 25.6% in subcutaneous tissue, and 16.3% in coelomic cavity. The results indicated that Spirometra severely infected snakes in food markets in Guangzhou and Shenzhen, implying that eating snakes has great health risk and improper cooking methods may increase the risk of Spirometra infection in humans in China. Additional steps should be considered by the governments and public health agencies to prevent the risk of snake-associated Spirometra infections in humans.

    The occurrence of platynosomiasis and intestinal sparganosis is described in feral cats from Grand Cayman, Cayman Islands. Spirometra spp. was observed within the intestine of 18.18% (10/55) of cats; 1.18% (1/55) of cats demonstrated gross and histological manifestation of parasitism by Platynosomum fastosum, but 14.5% (8/55) of cats had the characteristic pathological manifestations of P. fastosum-induced intrahepatic cholangitis without the concomitant presence of the intraductal trematode. Combined parasitism (Spirometra spp. and P. fastosum) was observed in 9.09% (5/55) of feral cats. Significant pathological findings were only associated with the hepatic fluke, P. fastosum, and were grossly characterized by moderate hepatomegaly with enlarged and dilated bile ducts. Examples of cestodes with morphological features characteristic of Spirometra spp. were observed within the small intestine without any associated pathological lesion. The histopathological evaluation of liver fragments revealed chronic intrahepatic cholangitis with and without the associated intraductal trematode, and was characterized by marked periductal fibrosis, adenomatous proliferation of bile duct epithelium, dilation of intrahepatic bile ducts and portal accumulations of inflammatory cells. The occurrence of the cestode in feral cats coupled with factors that are unique to Grand Cayman makes this island the ideal location for sporadic cases of human sparganosis.

    Cell signaling pathways that control proliferation and determine cell fates are tightly regulated to prevent developmental anomalies and cancer. Transcription factors and coregulators are important effectors of signaling pathway output, as they regulate downstream gene programs. In Caenorhabditis elegans, several subunits of the Mediator transcriptional coregulator complex promote or inhibit vulva development, but pertinent mechanisms are poorly defined. Here, we show that Mediator's dissociable cyclin dependent kinase 8 (CDK8) module (CKM), consisting of cdk-8, cic-1/Cyclin C, mdt-12/dpy-22, and mdt-13/let-19, is required to inhibit ectopic vulval cell fates downstream of the epidermal growth factor receptor (EGFR)-Ras-extracellular signal-regulated kinase (ERK) pathway. cdk-8 inhibits ectopic vulva formation by acting downstream of mpk-1/ERK, cell autonomously in vulval cells, and in a kinase-dependent manner. We also provide evidence that the CKM acts as a corepressor for the Ets-family transcription factor LIN-1, as cdk-8 promotes transcriptional repression by LIN-1. In addition, we find that CKM mutation alters Mediator subunit requirements in vulva development: the mdt-23/sur-2 subunit, which is required for vulva development in wild-type worms, is dispensable for ectopic vulva formation in CKM mutants, which instead display hallmarks of unrestrained Mediator tail module activity. We propose a model whereby the CKM controls EGFR-Ras-ERK transcriptional output by corepressing LIN-1 and by fine tuning Mediator specificity, thus balancing transcriptional repression vs. activation in a critical developmental signaling pathway. Collectively, these data offer an explanation for CKM repression of EGFR signaling output and ectopic vulva formation and provide the first evidence of Mediator CKM-tail module subunit crosstalk in animals.

  20. Pentastomiasis and other parasitic zoonoses from reptiles and amphibians.

    Reptiles are growing in popularity as pets.The colonization of reptiles and amphibians by parasites and the resulting disease conditions are the most common problems seen in captive animals.This review focuses on pentastomiasis and sparganosis, important parasitic zoonoses of reptiles and amphibians, respectively, and free living-amoebae. Humans are suitable accidental hosts for some pentastomid species (particularly Armillifer and Porocephalus). In geographical areas with special ethnics, such as in West and Central Africa, and East Asia, 8-45% of the human population can be affected. Usually the larvae are coincidentally found during abdominal surgeries. However, fatalities have been described. Extreme caution is necessary when handling infected reptiles. Ocular or cerebral sparganosis is not uncommonly found in humans in East Asia. This disease is caused by spargana, tapeworm larvae (plerocercoids) of Spirometra sp. The infection occurs when uncooked meat from reptiles or amphibians is applied to wounds or eyes and the parasites migrate directly to human tissue, or by consumption of contaminated food or water. As a consequence of the reptile's predatory behaviour, the full spectrum of endo- and ectoparasites from potential prey animals can be found as transiting parasites in the intestinal tract, e. g. Hymenolepis nana, Cryptosporidium (C.) muris, C parvum or Capillaria hepatica. Occasionally, free-living amoebae are also found in reptile faeces (Acanthamoeba, Naegleria, Hartmanella, Vahlkampfia or Echinamoeba sp.).

    LET-23 Epidermal Growth Factor Receptor (EGFR) signaling specifies the vulval cell fates during C. elegans larval development. LET-23 EGFR localization on the basolateral membrane of the vulval precursor cells (VPCs) is required to engage the LIN-3 EGF-like inductive signal. The LIN-2 Cask/LIN-7 Veli/LIN-10 Mint (LIN-2/7/10) complex binds LET-23 EGFR, is required for its basolateral membrane localization, and therefore, vulva induction. Besides the LIN-2/7/10 complex, the trafficking pathways that regulate LET-23 EGFR localization have not been defined. Here we identify vh4, a hypomorphic allele of agef-1, as a strong suppressor of the lin-2 mutant Vulvaless (Vul) phenotype. AGEF-1 is homologous to the mammalian BIG1 and BIG2 Arf GTPase guanine nucleotide exchange factors (GEFs), which regulate secretory traffic between the Trans-Golgi network, endosomes and the plasma membrane via activation of Arf GTPases and recruitment of the AP-1 clathrin adaptor complex. Consistent with a role in trafficking we show that AGEF-1 is required for protein secretion and that AGEF-1 and the AP-1 complex regulate endosome size in coelomocytes. The AP-1 complex has previously been implicated in negative regulation of LET-23 EGFR, however the mechanism was not known. Our genetic data indicate that AGEF-1 is a strong negative regulator of LET-23 EGFR signaling that functions in the VPCs at the level of the receptor. In line with AGEF-1 being an Arf GEF, we identify the ARF-1.2 and ARF-3 GTPases as also negatively regulating signaling. We find that the agef-1(vh4) mutation results in increased LET-23 EGFR on the basolateral membrane in both wild-type and lin-2 mutant animals. Furthermore, unc-101(RNAi), a component of the AP-1 complex, increased LET-23 EGFR on the basolateral membrane in lin-2 and agef-1(vh4); lin-2 mutant animals. Thus, an AGEF-1/Arf GTPase/AP-1 ensemble functions opposite the LIN-2/7/10 complex to antagonize LET-23 EGFR basolateral membrane localization and signaling

    Delay in diagnosis of pancreatic ductal adenocarcinoma (PDAC) is associated with decreased survival. The effect of an initial misdiagnosis on delay in diagnosis and stage of PDAC is unknown. This study is a retrospective review (2000-2010) from a University-based cancer center of new diagnoses of proximal PDAC. Of 313 patients, 98 (31.3 %) had an initial misdiagnosis. Misdiagnosed patients were younger, 62.8 ± 12.6 vs. 68.0 ± 10.1 (p < 0.001). The most common initial misdiagnoses were: gallbladder disease, gastroesophageal reflux disease, and peptic ulcer disease. After excluding patients with prior cholecystectomy, 14.2 % were misdiagnosed with gallbladder disease and underwent cholecystectomy before PDAC diagnosis. Misdiagnosed patients had higher rates of abdominal pain (p < 0.001), weight loss (p = 0.04), and acute pancreatitis (p < 0.001) and lower rate of jaundice (p < 0.001). Median time between symptoms to PDAC diagnosis was longer in misdiagnosed: 4.2 months vs. 1.4 (p < 0.001). Median time from contact with medical provider to axial imaging was longer in misdiagnosed (p < 0.001). Rate of stages III-IV disease at diagnosis was higher in misdiagnosed: 61.2 vs. 43.7 % (p = 0.004), with a 1.4 (95 % confidence interval (CI), 1.12-1.74) higher risk of stages III-IV disease at diagnosis; however, there was no difference in median overall survival in misdiagnosed patients (9.6 months in misdiagnosed vs. 10.3 months in correctly diagnosed, p = 0.69). Initial misdiagnosis of patients with proximal PDAC is associated with delay in diagnosis and higher risk of locally advanced or advanced disease at time of PDAC diagnosis.

    Cosmetic laser use has many pros and cons. The worldwide use of laser for body hair removal has led to many medical complications. Unsupervised use of the laser for hair removal in vulva may result in many problems and can merely damage the vulva, although rarely, affecting the body image. This rare and novel case report is a 21 year old virgin who presented with acute urinary retention and cryptomenorrhea due to complete synlabia secondary to unsupervised vulval laser hair removal. The urinary retention was relieved by suprapubic catheterization initially. During examination under anesthesia, the fused labia were separated by a surgical incision with drainage of hematocolpos and then, a Foley's urethral catheter was inserted. She had an uneventful recovery. We report this case to emphasize on the supervised use of laser by trained and qualified personnel for hair removal in vulva to minimize its complications.

    Yorkshire/Landrace crossbred gilts (N = 32) were evaluated using digital infrared thermal imaging (DITI) to discriminate between estrus and diestrus phases of the porcine estrous cycle. Gilts (N = 32) were part of an ongoing reproductive efficiency study involving the use of raw soybean (RSB; N = 15) versus soybean meal (SBM; N = 17) as a source of dietary protein. Gilts were monitored daily for signs of estrus using a teaser boar. Thermal images of vulva surface temperatures (TEMP) were recorded at standing estrus and diestrus. Measurements for analysis included minimum (MIN), maximum (MAX), mean (AVG), and standard deviation (SD) of temperature gradients. At imaging, ambient (AMB) and rectal temperatures (RT) were recorded, and blood samples taken for serum progesterone (P(4)) concentration analysis (by RIA) to confirm stage of cycle. Mean serum progesterone values at estrus and diestrus were (mean ± SD) 1.0 ± 0.1 and 10.9 ± 0.8 ng/mL, respectively. Vulva MIN, MAX, and AVG thermal images were positively correlated with one another (P < 0.01), and were positively correlated with ambient temperature (P < 0.01). Vulva MAX and AVG thermal temperatures were greater (P < 0.05) at estrus than at diestrus (36.6 ± 0.2 °C and 33.4 ± 0.3 °C vs. 35.6 ± 0.3 °C and 31.8 ± 0.6 °C, respectively), whereas MIN and SD had no differences (P > 0.05) between stages of the cycle. No differences (P > 0.05) in RT were detected between stages and RT was not significantly correlated with vulva thermal images. Diet had no significant effect on RT or vulva temperature.

    The nematode Caenorhabditis briggsae is an excellent model organism for the comparative analysis of gene function and developmental mechanisms. To study the evolutionary conservation and divergence of genetic pathways mediating vulva formation, we screened for mutations in C. briggsae that cause the egg-laying defective (Egl) phenotype. Here, we report the characterization of 13 genes, including three that are orthologs of Caenorhabditis elegans unc-84 (SUN domain), lin-39 (Dfd/Scr-related homeobox), and lin-11 (LIM homeobox). Based on the morphology and cell fate changes, the mutants were placed into four different categories. Class 1 animals have normal-looking vulva and vulva-uterine connections, indicating defects in other components of the egg-laying system. Class 2 animals frequently lack some or all of the vulval precursor cells (VPCs) due to defects in the migration of P-cell nuclei into the ventral hypodermal region. Class 3 animals show inappropriate fusion of VPCs to the hypodermal syncytium, leading to a reduced number of vulval progeny. Finally, class 4 animals exhibit abnormal vulval invagination and morphology. Interestingly, we did not find mutations that affect VPC induction and fates. Our work is the first study involving the characterization of genes in C. briggsae vulva formation, and it offers a basis for future investigations of these genes in C. elegans. PMID:23275885

    Influenza (flu) surveillance using Twitter data can potentially save lives and increase efficiency by providing governments and healthcare organizations with greater situational awareness. However, research is needed to determine the impact of Twitter users' misdiagnoses on surveillance estimates. This study establishes the importance of Twitter users' misdiagnoses by showing that Twitter flu surveillance in the United States failed during the 2011-2012 flu season, estimates the extent of misdiagnoses, and tests several methods for reducing the adverse effects of misdiagnoses. Metrics representing flu prevalence, seasonal misdiagnosis patterns, diagnosis uncertainty, flu symptoms, and noise were produced using Twitter data in conjunction with OpenSextant for geo-inferencing, and a maximum entropy classifier for identifying tweets related to illness. These metrics were tested for correlations with World Health Organization (WHO) positive specimen counts of flu from 2011 to 2014. Twitter flu surveillance erroneously indicated a typical flu season during 2011-2012, even though the flu season peaked three months late, and erroneously indicated plateaus of flu tweets before the 2012-2013 and 2013-2014 flu seasons. Enhancements based on estimates of misdiagnoses removed the erroneous plateaus and increased the Pearson correlation coefficients by .04 and .23, but failed to correct the 2011-2012 flu season estimate. A rough estimate indicates that approximately 40% of flu tweets reflected misdiagnoses. Further research into factors affecting Twitter users' misdiagnoses, in conjunction with data from additional atypical flu seasons, is needed to enable Twitter flu surveillance systems to produce reliable estimates during atypical flu seasons.

    Vulvar neoplasms represent four percent of all gynecological cancers. While most cases of vulvar neoplasms are benign, two percent of patients present with malignant disease. We present the case of a 37-year-old premenopausal female who presented to an outside institution with a lump in her left vulva, which had progressively enlarged to the size of an egg. A wide local excision of the left vulva was performed, and the pathology revealed a high-grade sarcoma, not otherwise specified (NOS), with negative margins. Imaging showed enlarged bilateral external iliac lymph nodes, likely metastatic. After discussion at a multidisciplinary gynecology oncology tumor board, she was treated with gemcitabine/docetaxel chemotherapy, followed by a left inguinal lymph node dissection and a left radical vulvectomy after being referred to our centre. The final pathology at that time showed a residual sarcoma of 3.5 mm in the left vulva with no lympho-vascular invasion (LVI) and negative margins, with the closest, laterally, at 2 mm. A total of three lymph nodes were negative. She received additional chemotherapy postoperatively. Approximately one year later, she returned to her gynecologist with a 1 cm mass on the left vulva. She underwent a left hemi-vulvectomy and lymph node dissection, and pathology confirmed the presence of a high-grade sarcoma with close margins. She received adjuvant radiotherapy. Three months later, she presented with persistent cough and pneumonia. Imaging revealed a 10 cm lung mass, which was believed to be metastasis from the vulva. This was confirmed with biopsy and was completely resected. Any mass in the Bartholin gland area should be investigated carefully. Poorly differentiated vulvar leiomyosarcoma in the Bartholin gland can recur locally but may also lead to distant metastasis. Despite surgical and systemic treatment, as well as adjuvant radiation, the tumor recurred. Due to the rarity of this condition, there are no clear recommendations for

    Species of the genus Spirometra are diphyllobothriid tapeworms with complex life cycles and are involved in human sparganosis, a neglected disease that affects individuals worldwide. Although some species were reported in wild felids and human cases of sparganosis were described in Brazil, the biology and taxonomy of these parasites are poorly understood. In the present study, samples of diphyllobothriids (eggs and/or proglottids) obtained from the stools of wild carnivores (Leopardus pardalis and Lycalopex vetulus) and plerocercoid larvae found in a snake (Crotalus durissus) from Brazil were analysed by amplifying a fragment of the gene cytochrome c oxidase subunit 1 (cox 1). The DNA sequences obtained here for the first time from the Spirometra spp. from Brazil were used to evaluate the phylogenetic relationships with other species. Molecular data identified two species in the Brazilian samples (evolutionary divergence of 17.8-19.2%). The species were identified as Spirometra sp. 1, found in Le. pardalis, and Spirometra sp. 2 found in Ly. vetulus and C. durissus, and they differed from Asian isolates of Spirometra erinaceieuropaei (17.5-20.2% and 12.2-15.6%, respectively), a species previously considered to be distributed worldwide. Moreover, Spirometra sp. 1 is genetically distinct from Sparganum proliferum from Venezuela (19.6-20.4%), while Spirometra sp. 2 is more closely related with the Venezuelan species (6.1-7.0%). Sequences of Spirometra sp. 2 revealed that it is conspecific with the Argentinean isolate of Spirometra found in Lycalopex gymnocercus (1.9-2.2%). Taxonomic and phylogenetic aspects related to New World species of Spirometra are briefly discussed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The pars intermedia is an area of the vulva that has been inconsistently described in the literature. We conducted anatomic studies to better describe the tissues and vascular structures of the pars intermedia and proposed a functional rationale of the pars intermedia in the female sexual response. Nine cadaveric vulvectomy specimens were used. Each was serially sectioned and stained with hematoxylin and eosin and Masson's trichrome. Histologic ultrastructural description of the pars intermedia. The pars intermedia contains veins traveling longitudinally in the angle of the clitoris, supported by collagen-rich stromal tissues. These veins drain the different vascular compartments of the vulva, including the clitoris, the bulbs, and labia minora; also, the interconnecting veins link the different vascular compartments. The pars intermedia is not composed of erectile tissue, distinguishing it from the erectile tissues of the corpora cavernosa of the clitoris as well as the corpus spongiosum of the clitoral (vestibular) bulbs. The venous communications of the pars intermedia, linking the erectile tissues with the other vascular compartments of the vulva, appear to provide the anatomic basis for a coordinated vascular response during female sexual arousal. © 2012 International Society for Sexual Medicine.

    The aim of this study was to determine the influence of menstruation on the bacterial population of healthy Japanese women's vulvas, especially the labia minora. Labia minora swabs were obtained from 10 premenopausal, nonpregnant Japanese women at premenstruation and on day 2 of menstruation. Vaginal swabs were also obtained from 3 out of the 10 women. No significant difference was found in the average bacterial cell count between the menstruation and premenstruation samples. Molecular analysis using a 16S rRNA gene-based clone library method detected 22 genera from the labia minora swabs (total 20), with the genus Lactobacillus being predominant at both premenstruation and during menstruation in 7 out of the 10 women. Of the other 3 women, 2 showed various kinds of bacterial species, including oral and fecal bacteria, with Atopobium vaginae and Gardnerella vaginalis predominating in the remaining woman's vulva in both conditions. In total, 6 out of 10 cases (60%) showed significantly different microbiota of the labia minora between the two conditions. These results imply that menstruation may promote a distortion of the bacterial flora around the vulva, although it causes no significant increase of the bacterial count.

    Merkel cell carcinoma is a rare and aggressive neoplasm originating from mechanoreceptor Merkel cells of the stratum basale of the epidermis. Cases affecting the vulva are exceedingly rare, with the currently available literature primarily in case report form. Systematic review of the PubMed database returned 17 cases of Merkel cell carcinoma affecting the vulva. Patients presented at a mean age of 59.6 years with a firm, mobile vulvar mass. Symptoms of pain, erythema, pruritus, edema, and ulceration have been reported. Tumor histology is consistent with that of neuroendocrine tumors and typical Merkel cell carcinomas. Neuroendocrine and cytokeratin immunostains are frequently utilized in histopathological workup. Surgical management was the unanimous first-line therapy with adjuvant radiation in most cases. Recurrence occurred in 70.6% of patients at a mean follow-up of 6.3 months. Mortality was at 47.0% at a mean of 7.8 months after initial operation. Merkel cell carcinoma affecting the vulva is an extremely rare and highly aggressive neoplasm. The present review of published cases serves to comprehensively describe the clinical course and treatment approaches for vulvar Merkel cell carcinoma.

    Vaginal cytology and vulva size were used to characterize the reproductive cycle of female black-footed ferrets (Mustela nigripes), Siberian polecats (M. eversmanni), and domestic ferrets (M. putorius furo). Emphasis was on black-footed ferrets because of the need to breed these critically endangered animals and on Siberian polecats because of the close taxonomic relationship to black-footed ferrets. Vaginal cytology of the 3 species of ferret is similar. Proestrus was characterized by an increasing percentage of superficial epithelial cells and enlargement of the vulva. During estrus, superficial cells were usually greater than or equal to 90% of epithelial cells in the vaginal lavage and after several days were fully keratinized. Neutrophils were more common during all stages of the estrous cycle in domestic ferrets than they were in the other species. Following copulation, percentage of superficial calls in the vagina declined and vulva swelling subsided. Large cells, probably of uterine symplasma origin, were observed in vaginal lavages following whelping or pseudopregnancy. Vaginal cytology is extremely useful in the reproductive management of black-footed ferrets and Siberian polecats. Knowledge of normal vaginal cytology could be applied to the diagnosis of female reproductive abnormalities in all 3 species.

  19. [KAPOSI'S SARCOMA OF THE VULVA].

    2015-01-01

    Kaposi's sarcoma represents multiple idiopathic hemorrhagic sarcoma--a mesenchymal tumor that affects the blood and lymph vessels. Its performance is associated with an infection with human herpes virus type 8--the so called KSHV (Kaposi's sarcoma -associated virus), and with the human immunodeficiency virus. Kaposi's sarcoma is considered as a typical clinical manifestation in male homosexuals suffering from acquired immune deficiency syndrome (AIDS), while his performance in HIV-positive women is unusual, with a ratio of men to women--10-15: 1. Vulvar localization is much rarer. It is up to 5 times more frequent in HIV- positive patients. It is clinically represented in most of the cases by the clinical picture of nonspecific tumor mass. Biopsy and further virological testing for establishing KSHV in lesional tissue is essential for confirming the diagnosis. Serological testing for HIV/AIDS in affected patients is required. Local treatment includes surgical excision of solitary lesions, cryotherapy as well as radiotherapy. The use of interferon alpha resulted in complete remission in approximately 40% of the affected patients. New trends in treatment tend to be pathogenetically directed as in the process of studies to date are inhibitors of angiogenesis. Due to the rarity of the occurrence, non-specific clinical picture and histological findings, Kaposi's sarcoma should be considered in the differential diagnosis of tumor masses with vulvar localization, especially in HIV-positive patients.

    Cerebellar infarction is easily misdiagnosed or underdiagnosed. In this study, we investigated factors leading to misdiagnosis of cerebellar infarction in patients with acute ischemic stroke. Data on neurological and radiological findings from 114 consecutive patients with acute cerebellar infarction were analyzed. We investigated factors associated with misdiagnosis from the data on clinical findings. Thirty-two (28%) patients were misdiagnosed on admission. Misdiagnosis was significantly more frequent in patients below 60 years of age and in patients with vertebral artery dissection, and significantly less frequent in patients with dysarthria. It tended to be more frequent in patients with the medial branch of posterior inferior cerebellar artery territory infarction, and infrequent in patients with the medial branch of the superior cerebellar artery territory infarction. Thirty out of 32 (94%) misdiagnosed patients were seen by physicians that were not neurologists at the first visit. Twenty-four of 32 (75%) misdiagnosed patients were screened only by brain CT. However, patients were not checked by brain MRI or follow-up CT until their conditions worsened. Patients below 60 years of age and patients with vertebral artery dissection are more likely to have a cerebellar infarction misdiagnosed by physicians other than neurologists.

    Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) causes swelling in the skin and upper airways and pain in the abdomen because of mucosal swelling. C1-INH-HAE is frequently misdiagnosed, leading to delays in diagnosis, inadequate treatment, and unnecessary procedures. To evaluate the history of misdiagnosis in patients participating in the Icatibant Outcome Survey (IOS). The IOS is an observational study in which safety and effectiveness of icatibant have been evaluated since 2009. As part of the IOS, patients record any misdiagnoses received before being diagnosed as having C1-INH-HAE. In January 2016, a total of 418 of 633 IOS patients with C1-INH-HAE type I or II had provided misdiagnosis data. Of these, 185 of 418 (44.3%) received 1 or more prior misdiagnoses. The most common misdiagnoses were allergic angioedema (103 of 185) and appendicitis (50 of 185). A variety of other misdiagnoses were reported, including a substantial number of gastrointestinal disorders (excluding appendicitis). Misdiagnosis rates were similar between males (41.1%) and females (46.5%) and between C1-INH-HAE type I (43.7%) and type II (51.6%). Patients with family members diagnosed as having C1-INH-HAE were significantly less likely to be misdiagnosed than patients without a family history (140 of 366 [41.7%] vs 38 of 58 [65.5%], respectively; P = .001). Patients with a prior misdiagnosis had longer median delay to C1-INH-HAE diagnosis (13.3 years) than patients without (1.7 years; P < .001). From this large database, approximately 50% of patients with C1-INH-HAE type I or II have previously had their conditions misdiagnosed, most commonly as allergic angioedema or appendicitis. Misdiagnosis results in marked delays in receiving the correct diagnosis, during which time patients cannot access effective, lifesaving treatment. ClinicalTrials.gov: NCT01034969.

  2. If there’s a penis, it’s most likely a man: Investigating the social construction of gender using eye tracking

    In their foundational work on the social construction of gender, Kessler and McKenna (1978) investigated the relationship between gender attribution and genital attribution. We used digital reproductions of the original stimuli to replicate their findings in the current social context. To further investigate the underlying decision processes we applied eye tracking. The stimuli shown varied in the composition of gender cues: from those more commonly associated with maleness to associated with femaleness. Applying the ethnomethodological approach originally used, participants were asked to decide for each stimulus whether they saw a man or a woman and to indicate subjective confidence with the decision. In line with the original results we found that the genital attribution contributed immensely to the gender attribution. Also, male gender was ascribed more often when the penis was present than was female gender when the vulva was shown. Eye tracking revealed that overall most dwell time as a proxy for important information was dedicated to the head, chest and genital areas of all the stimuli. Total dwell time depended on whether the gender attribution was made in line with the depicted genital, if the genital was a penis. Attributing female gender when a penis was present was associated with longer total dwell time, unlike attributing male gender with a vulva shown. This is indicative of higher cognitive effort and more difficulty ignoring the penis as opposed to the vulva. We interpret this finding in context of the persistent male dominance as well as to the socio-cultural understanding of the vulva as a concealed and therefore seemingly absent organ. In summary, we were able to show that the gender attribution is still closely linked to genital attribution when having a binary forced choice task and that the penis is a special cue in this attribution process.

    To analyze the cause of misdiagnosis of occupational chronic n-hexane poisoning and to investigate the diagnosis and differential diagnosis of this disease. The clinical data of 16 patients with occupational chronic n-hexane poisoning who had been misdiagnosed with other diseases were collected. The hospital they first visited, cause of misdiagnosis, clinical features, and the misdiagnosis rate among inpatients during the same period were retrospectively analyzed. Sixteen of 62 patients hospitalized during the same period were misdiagnosed at the first visit; 11 cases were in the upper first-class hospitals, and 5 cases in the upper second-class hospitals; 5 cases were misdiagnosed as Green Barry syndrome, 2 cases as motor neuron disease, 2 cases as drug-induced peripheral neuropathy, 3 cases as periodic paralysis, and 4 cases had uncertain diagnosis. Most doctors who work in ordinary hospitals do not know occupational chronic n-hexane poisoning, which is often misdiagnosed as general neuropathies or difficult diseases. The key to correct diagnosis is to know the patient's occupational history and clinical features.

    Treatment of locally advanced vulva cancer (LAVC) remains challenging. Due to the lack of randomised trials many questions regarding the indications for different treatment options and their efficacy remain unanswered. In this retrospective study we provide the largest published series of LAVC patients treated with anovulvectomy, reporting oncological outcomes and morbidity. Additionally, a systematic literature review was performed for all treatment options 1946-2015. In our case series, 57/70 (81%) patients were treated in the primary setting with anovulvectomy and 13 patients underwent anovulvectomy for recurrent disease. The median overall survival (OS) was 69months (1-336) with disease specific survival of 159months (1-336). Following anovulvectomy for primary disease, time to progression and OS were significantly higher in node negative disease (10 vs. 96months; 19 vs. 121months, p<0.0001). Post-surgical complications were observed in 36 (51.4%), the majority of which were Grade I/II infections. There was one peri-operative death. Review of the literature showed that chemotherapy, radiotherapy or combination treatments are alternatives to surgery. Evidence relating to all of these consisted mostly of small retrospective series, which varied considerably in terms of patient characteristics and treatment schedules. Significant patient and treatment heterogeneity prevented meta-analysis with significant biases in these studies. It was unclear if survival or morbidity was better in any one group with a lack of data reporting complications, quality of life, and long term follow-up. However, results for chemoradiation are encouraging enough to warrant further investigation. There remains inadequate evidence to identify an optimal treatment for LAVC. However, there is sufficient evidence to support a trial of anovulvectomy versus chemoradiation. Discussions and consensus would be needed to determine trial criteria including the primary outcome measure. Neoadjuvant

    We present the clinical and pathological findings of 6 women with intraepithelial neoplasia of differentiated or simplex type (DVIN). The mean age was 68 years (range 55-82). One lesion was still in situ, whereas 5 were associated with squamous carcinoma, 4 of well-differentiated keratinizing type and 1 of poorly differentiated spindle-cell type. The invasive depth of the squamous carcinomas ranged from 0.6 to 8 mm and the surgical margins of all of the resection specimens were uninvolved by neoplastic cells. In contrast, DVIN involved the surgical margins in 5 specimens while the remaining specimen had normal surgical margins. In all 6 vulvar specimens, DVIN showed intense immunoreactivity for Ki-67 in the basal and parabasal cells while only 4 specimens showed reactivity for p53. In 5 surgical specimens with DVIN the number of CD1a cells was increased but little if any immunoreactivity could be found amongst the corresponding invasive neoplastic cells. Four squamous carcinomas also showed diffuse p53 reactivity. There was little difference in the pattern of Ki-67 expression between DVIN and squamous carcinoma. For a number of reasons, DVIN present diagnostic difficulty and considerable interobserver variation also exists. Our study suggests that Ki-67 and p16 are useful for distinguishing DVIN and classical VIN 3, whereas p53 and CD1a are useful for distinguishing DVIN and invasive squamous carcinoma. Furthermore, p53 appears to have higher specificity than sensitivity for distinguishing DVIN from normal squamous epithelium.

    Female sexual arousal disorder is a pathophysiologic state characterized clinically by persistent or recurrent inability to attain or maintain an adequate lubrication-swelling response of sexual excitement until completion of sexual activity. Prior clinical experience with alprostadil products for men with erectile dysfunction supports its use in women with female sexual arousal disorder. To compare the effect of topical alprostadil with over-the-counter (OTC) lubricant on female genital arousal in the absence of visual sexual stimuli. Healthy premenopausal women without sexual dysfunction were recruited from the community to participate in the study. Of 17 women who consented, 10 were enrolled and completed the trial. The mean age of subjects was 32 years (range = 27-43). Study drug or placebo was applied topically to the genitals. Continuous temperature monitoring was performed. Participants completed questionnaires assessing genital sensation, effect, intensity, and duration. Change in temperature from baseline in vestibule, clitoris and vulva. In all 10 subjects, topical alprostadil induced a statistically significant increase in temperature of the vestibule, clitoris, and vulva compared with the OTC lubricant. The most rapid difference in genital temperature between placebo and alprostadil was seen on the vulva, which demonstrated a significant difference at approximately 9 minutes. There was a significant difference in temperature seen for the vestibule and clitoris at 11 and 19 minutes, respectively. Sixty percent of women reported being aware or conscious of genital sensations with topical alprostadil, but not with OTC lubricant. Discordance was noted in 30% of subjects who reported being aware or conscious of genital sensations with the two treatments and 10% who reported not being aware or conscious of genital sensations with either treatment. Topical alprostadil administered to healthy premenopausal women induced statistically significant, sustained

  10. DOP-2 D2-Like Receptor Regulates UNC-7 Innexins to Attenuate Recurrent Sensory Motor Neurons during C. elegans Copulation

    Neuromodulation of self-amplifying circuits directs context-dependent behavioral executions. Although recurrent networks are found throughout the Caenorhabditis elegans connectome, few reports describe the mechanisms that regulate reciprocal neural activity during complex behavior. We used C. elegans male copulation to dissect how a goal-oriented motor behavior is regulated by recurrently wired sensory-motor neurons. As the male tail presses against the hermaphrodite's vulva, cholinergic and glutamatergic reciprocal innervations of post cloaca sensilla (PCS) neurons (PCA, PCB, and PCC), hook neurons (HOA, HOB), and their postsynaptic sex muscles execute rhythmic copulatory spicule thrusts. These repetitive spicule movements continue until the male shifts off the vulva or genital penetration is accomplished. However, the signaling mechanism that temporally and spatially restricts repetitive intromission attempts to vulva cues was unclear. Here, we report that confinement of spicule insertion attempts to the vulva is facilitated by D2-like receptor modulation of gap-junctions between PCB and the hook sensillum. We isolated a missense mutation in the UNC-7(L) gap-junction isoform, which perturbs DOP-2 signaling in the PCB neuron and its electrical partner, HOA. The glutamate-gated chloride channel AVR-14 is expressed in HOA. Our analysis of the unc-7 mutant allele indicates that when DOP-2 promotes UNC-7 electrical communication, AVR-14-mediated inhibitory signals pass from HOA to PCB. As a consequence, PCB is less receptive to be stimulated by its recurrent synaptic partner, PCA. Behavioral observations suggest that dopamine neuromodulation of UNC-7 ensures attenuation of recursive intromission attempts when the male disengages or is dislodged from the hermaphrodite genitalia. SIGNIFICANCE STATEMENT Using C. elegans male copulation as a model, we found that the neurotransmitter dopamine stimulates D2-like receptors in two sensory circuits to terminate futile

    Although occasionally difficult, distinguishing abdominal neuroblastoma (NBL) from Wilms tumor (WT) at presentation is important, as surgical management differs significantly. We reviewed our 20-year experience (1987-2006) treating patients with NBL, focusing on those with an initial diagnosis of WT, to determine presenting features that would have suggested the correct preoperative diagnosis. Retrospective case cohort study reviewing charts and imaging of patients with NBL initially diagnosed clinically with WT. Preoperative symptoms, laboratory studies, and imaging were evaluated. Similar variables were assessed in the 20 patients with WT most recently treated at our institution. Nine patients with NBL were identified as those who had an exploratory laparotomy with a preoperative diagnosis of WT; 8 underwent nephrectomy at exploration. Children with NBL had symptoms such as fever and weight loss at presentation (67%) more often than patients with WT (20%). Preoperative computed tomography demonstrated intratumoral calcifications, vascular encasement, or both in 78% of patients with NBL but were never seen in WT patients. Of interest, preoperative urinary catecholamines were elevated in 5 patients ultimately diagnosed with NBL. Although NBL can be mistaken for WT at presentation, the presence of constitutional symptoms, or intratumoral calcification or vascular encasement on preoperative imaging should heighten suspicion for NBL. In addition, laboratory evaluation, including urinary catecholamines, should be completed before surgery when the etiology of an abdominal tumor is uncertain.

We report the case of a man aged 22 years with no risk factors, erroneously diagnosed with, and treated for, toxoplasmosis on the basis of consistent lymph node histology. The correct diagnosis was delayed by the dramatic symptomatic improvement resulting from this therapy. Whipple's disease should be considered in cases of granulomatous lymphadenopathy of unknown cause, even if the age of the patient does not fit the classic presentation of the disease. 2017 BMJ Publishing Group Ltd.

    Objective: The aim of this study is to explore the misdiagnosis status of the otolaryngology in China as well as to provide evidence to reduce misdiagnosis and improve the diagnostic level. Method: The retrieval and management system of the misdiagnosed diseases database developed by Chen Xiaohong was used for searching the literature of the misdiagnosis in otolaryngology.The 10 year' smisdiagnosis literature data of the otolaryngology(from 2004 to 2013) were analyzed including the literature sources, sample size, misdiagnosis rate,misdiagnosis consequences and misdiagnosis reasons. Result: A total of 369 articles were found,including 4211 cases.The average misdiagnosis rate was 25.43% in 51 diagnosed diseases.The top misdiagnosed diseases were nasopharyngeal tuberculosis(84.76%),tuberculous otitis media (75%) and congenital laryngeal cyst(75%).The lowest misdiagnosed disease was nasosinusitis(5.92%).The top three misdiagnosed diseases were tuberculosis of otolaryngology(1216 cases),nasosinusitis(710 cases) and BPPV(697 cases).After statistical analysis,we found that 97.22% of the misdiagnosed patients were grade Ⅲ consequences (that is the misdiagnosis and mistreatment does not cause adverse consequences),but there were still 10 cases caused gradeⅠconsequences(death or sequela).The main causes of the misdiagnosis were lack of diagnosis experience, non detailed interrogation and physical examination and non targeted examinations. Conclusion: The big data of the 10 years reflects the misdiagnosis phenomenon in otolaryngology to some extent.Neurologist, stomatologist and ophthalmologist should be familiar to the main points of the differential diagnosis diseases of the otolaryngology and strive to reduce the clinical misdiagnosis and mistreatment.

    To characterize patients misdiagnosed with multiple sclerosis (MS). Neurologists at 4 academic MS centers submitted data on patients determined to have been misdiagnosed with MS. Of 110 misdiagnosed patients, 51 (46%) were classified as "definite" and 59 (54%) "probable" misdiagnoses according to study definitions. Alternate diagnoses included migraine alone or in combination with other diagnoses 24 (22%), fibromyalgia 16 (15%), nonspecific or nonlocalizing neurologic symptoms with abnormal MRI 13 (12%), conversion or psychogenic disorders 12 (11%), and neuromyelitis optica spectrum disorder 7 (6%). Duration of misdiagnosis was 10 years or longer in 36 (33%) and an earlier opportunity to make a correct diagnosis was identified for 79 patients (72%). Seventy-seven (70%) received disease-modifying therapy and 34 (31%) experienced unnecessary morbidity because of misdiagnosis. Four (4%) participated in a research study of an MS therapy. Leading factors contributing to misdiagnosis were consideration of symptoms atypical for demyelinating disease, lack of corroborative objective evidence of a CNS lesion as satisfying criteria for MS attacks, and overreliance on MRI abnormalities in patients with nonspecific neurologic symptoms. Misdiagnosis of MS leads to unnecessary and potentially harmful risks to patients. Misinterpretation and misapplication of MS clinical and radiographic diagnostic criteria are important contemporary contributors to misdiagnosis. © 2016 American Academy of Neurology.

    Primary vulvar adenocarcinomas are rare tumors, and their histogenesis is not fully understood. They are classified into extramammary Paget's disease, sweat gland carcinomas, and "breast-like" adenocarcinomas of the vulva. The latter resemble adenocarcinomas arising in the breast morphologically and immunophenotypically. Rare cases of adenocarcinoma with apocrine features have been reported, and whether these neoplasms originate from the "native apocrine" sweat glands or from "anogenital mammary-like" glands are still debatable. The presence of normal mammary-like glands in the vicinity of the tumor, the transitional malignant morphological features from normal mammary-like glands and the tumor, the breast-like histological features of the tumor, and the expression of estrogen and progesterone receptors generally suggest an origin from anogenital mammary-like glands. Absence of these features points toward native apocrine sweat glands as the source of these neoplasms. In this report, we present a patient who was initially diagnosed with Paget's disease of the right vulva, which was treated by hemi-vulvectomy, and who later presented with primary vulvar apocrine adenocarcinoma with metastasis to the inguinal lymph nodes and intranodal mucinous/colloidal differentiation: a feature, to the best of our knowledge, not reported before. We also reviewed the histogenesis of the vulvar adenocarcinomas, with emphasis on the morphological features that separate the tumors arising from the anogenital mammary-like glands in the vulva from those arising from the native vulvar sweat glands.

    Richner-Hanhart syndrome (RHS, tyrosinemia type II) is a rare, autosomal recessive inborn error of tyrosine metabolism caused by tyrosine aminotransferase deficiency. It is characterized by photophobia due to keratitis, painful palmoplantar hyperkeratosis, variable mental retardation, and elevated serum tyrosine levels. Patients are often misdiagnosed with herpes simplex keratitis. We report on a a boy from Brazil who presented with bilateral keratitis secondary to RHS, which had earlier been misdiagnosed as herpes simplex keratitis.

    First branchial arch cysts are uncommon. Therefore, together with its variable clinical and age presentation they are often misdiagnosed at first. The treatment is surgical, requiring a correct procedure to avoid future recurrences. In this paper we describe a typical case of first branchial arch cyst in which as described in other reports, we first made several misdiagnoses and therefore an inadequate treatment and lastly, with the correct diagnosis, we performed a meticulous complete excision under facial nerve monitoring.

    Summary: In this case report we describe the use of a 2-stage approach to treat severe recurrent vulvar lymphangiectasia in a patient with Noonan syndrome. First, 3 functional lymphatic vessels were identified and anastomosed to venules in an end-to-end fashion. Then, in a second surgical procedure, the vulvar lesions were resected as much as possible and the vulva was reconstructed. By the 12-month follow-up the patient had recovered well. Although there were still some small vesicles on the left labia there was no more ooze, itch, and pain. Lymphatic mapping using indocyanine green showed improvement of the edema of her vulva region and patent LVA. In addition to the demonstration of this 2-stage approach, this case report also demonstrates the benefits of preemptive LVA before performing surgery that may be at high risk for postoperative lymph edema.

    Pruritus, or itch, is a common vulvar complaint that is often treated empirically as a yeast infection; however, yeast infections are just one of the many conditions that can cause vulvar itch. Ignoring other conditions can prolong pruritus unnecessarily. Atopic dermatitis, irritant contact dermatitis, and allergic contact dermatitis are extremely common noninfectious causes of vulvar itch that are often underdiagnosed by nondermatologists. Identifying these conditions and treating them appropriately can significantly improve a patient's quality of life and appropriately decrease health care expenditures by preventing unnecessary additional referrals or follow-up visits and decreasing pharmaceutical costs.

    We present our experience at University of Chile Clinical Hospital, about superficial scamous vulvar carcinoma, during January, 1967 and april, 1992. We studied eight patients, mean age 57.1 years. Diagnostic was histopathologic in all cases. Three patients were submitted to simple total vulvectomy; other three were treated by total vulvectomy and bilateral inguinal lymphadenectomy (classic form of treatment). The other two cases, were submitted to simple in one case and partial vulvectomy in other, with lymphadenectomy by separate bilateral inguinal incisions. Histopathological study proved in situ scamous carcinoma near invasive focus at 50% of all cases. Follow up was between 2 and 25 years, mean 10.5 years. In one patient, carcinoma in situ relapsed at 2 years and 8 months after treatment, and then, at 8 years after primitive treatment. In other patient, and anal carcinoma was demonstrated 20 years after vulvectomy.

    The standard radical mutilating surgery for the treatment of invasive vulval carcinoma is, today, being replaced by a conservative and individualised approach. Surgical conservative modifications that are currently considered safe, regarding vulval lesion, are separate skin vulval-groin incisions, drawn according to the lesion diameter, and wide local radical excision or partial radical vulvectomy with 1-2 cm of clinically clear surgical margins. Regarding inguinofemoral lymph nodes management, surgical conservative modifications not compromising patient survival are omission of groin lymphadenectomy only when tumour stromal invasion is ≤ 1 mm, unilateral groin lymphadenectomy only in well-lateralised early lesions and total or radical inguinofemoral lymphadenectomy with preservation of femoral fascia when full groin resection is needed. Sentinel lymph node dissection is a promising technique but it should not be routinely employed outside referral centres. Pelvic nodes are better managed by radiation. Locally advanced vulval carcinoma can be managed by ultraradical surgery, exclusive radiotherapy or chemoradiation. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The purpose of this study was to characterize male preferences of vulvar appearance, their awareness of labiaplasty, and their knowledge of genital anatomy. Men 18-80 years old were recruited via emails sent by an Internet provider to participate in a 27-question web-based survey. The questionnaire included images and queried demographics, men's familiarity with vulvar anatomy, preferences regarding labial appearance, and awareness of labiaplasty. Two deployments to >150,000 email addresses were sent. Demographic data were described using frequencies for categoric variables and mean measures of central tendency for continuous variables. Logistic regression models were used to analyze associations between demographics and responses. Two thousand four hundred three men responded to the survey. After excluding incomplete and ineligible surveys, 1847 surveys were analyzed. The median age of respondents was 55 years. The majority was white (87%), married (68%), employed (69%), and had completed high school or beyond (97%). One-third of the respondents lived in the South, with the other regions nearly equally represented. A significant majority, 95%, reported having been sexually active with women, and 86% felt comfortable labeling the vulvar anatomy. With regard to preferences, more respondents considered smaller labia attractive compared to large labia; yet 36% of the men remained neutral. Men also showed a preference for partially or completely groomed genitals compared to natural hair pattern. Whereas 51% of participants believed the appearance of a woman's labia influenced their desire to engage in sexual activity, 60% denied it affected sexual pleasure. Only 42% of men were familiar with labiaplasty, and 75% of all respondents would not encourage a female partner to change her genital appearance. Multivariable analysis revealed younger age to be associated with preferences for small labia and complete genital hair removal, as well as familiarity with labiaplasty. In this national survey, men demonstrated familiarity with the female anatomy, but many did not feel it impacted sexual desire or pleasure. Moreover, the majority lacked strong preferences for a specific vulvar appearance and would not encourage a female partner to alter her genital appearance surgically. Copyright © 2015 Elsevier Inc.

    Tapeworms of the genus Spirometra include species whose larval stages can infect humans, causing a disease called sparganosis. Cases of human infection with adult worms are very rare and have been reported in Korea and China. Here we report the first case of human infection with an adult of Spirometra erinaceieuropaei in Vietnam. A 23-year-old male was admitted to 103 Military Hospital, Hanoi, Vietnam with fever, weight loss and epigastric discomfort. Preliminary diagnosis based on discovery of parasite eggs in his faeces incorrectly determined a fluke as the agent of the infection and praziquantel was prescribed. Two days later he passed out proglottids in his stool. The tapeworm was identified as Spirometra erinaceieuropaei using morphological and molecular tools. This is the first case of human infection with adult worm of Spirometra erinaceieuropaei in Vietnam.

    A 59 years old woman was admitted in our unit accusing longtime dysphagia and regurgitation. On admission, the patient was wearing a 3 month old definitive feeding gastrostomy tube. The contrast swallow, endoscopy and esophageal manometry established the diagnostic--achalasia. We removed the gastrostomy tube and we performed an open Heller myotomy. The postoperative period was uneventful and the patient was discharged one week later with affirmatively unimpaired deglutition. One month later, the patient was admitted via emergency with a giant fibrous tumor arising from her mouth after an episode of strong coughing and vomiting. The repeated endoscopy showed a giant esophageal polyp that was missed by the previous investigations, originating from pharingoesophageal junction. The esophageal polyp was resected by cervical approach with good postoperative outcome. The polyp's particular extreme dimensions (27 cm) prevented the acute asphyxia by blockage at the laryngeal level, possibly provoked by smaller tumors. As postoperative one month barium swallow showed a normal esophageal aspect, a final question remains--was achalasia real or an erroneous diagnosis was established the second time too?

  20. Foot fractures frequently misdiagnosed as ankle sprains.

    PubMed

    2002-09-01

    Most ankle injuries are straightforward ligamentous injuries. However, the clinical presentation of subtle fractures can be similar to that of ankle sprains, and these fractures are frequently missed on initial examination. Fractures of the talar dome may be medial or lateral, and they are usually the result of inversion injuries, although medial injuries may be atraumatic. Lateral talar process fractures are characterized by point tenderness over the lateral process. Posterior talar process fractures are often associated with tenderness to deep palpation anterior to the Achilles tendon over the posterolateral talus, and plantar flexion may exacerbate the pain. These fractures can often be managed nonsurgically with nonweight-bearing status and a short leg cast worn for approximately four weeks. Delays in treatment can result in long-term disability and surgery. Computed tomographic scans or magnetic resonance imaging may be required because these fractures are difficult to detect on plain films.

    An enhanced visualization technique using polarized light (Syris v600 enhanced visualization system; Syris Scientific LLC, Gray, ME) detects surface and subsurface ( approximately 1 mm depth) inflammation. We sought to compare the Syris v600 system with unaided visual inspection and colposcopy of the female genitalia. Erythema and dryness of the vulva, introitus, vagina, and cervix were visualized and scored by each method in patients with and without vulvitis. Subsurface visualization was more sensitive in detecting genital erythema and dryness at all sites whether or not symptoms were present. Subsurface inflammation of the introitus, vagina, and cervix only was detected uniquely in women with vulvar vestibulitis syndrome (VVS). A subset of women presenting with VVS exhibited subclinical inflammation of the vulva vestibule and vagina (designated VVS/lichen sclerosus subgroup). Enhanced visualization of the genital epithelial subsurface with cross-polarized light may assist in diagnosing subclinical inflammation in vulvar conditions heretofore characterized as sensory syndromes.

    Imperforate hymen typically presents in adolescence with pain, hematocolpometra and primary amenorrhea. This case documents a previously unreported etiology for an atypical presentation with a history of recent menstruation. A female adolescent presented with symptoms of urinary retention and leg pain. She reported a history of irregular, painful menses. Clinical examination revealed a pelvic mass and imperforate hymen. Sonography was consistent with hematocolpometra. Before a planned hymenectomy, the patient began to pass dark blood through a fistulous opening in her vulva. Hymenectomy resulted in complete resolution of the pain and hematocolpometra. Identification of the fistulous tract explained the patient's history of menstrual bleeding despite an imperforate hymen. Spontaneous rupture of hematocolpometra through a fistulous tract to the vulva is a previously unreported atypical presentation of imperforate hymen in a "menstruating" adolescent with pain and a pelvic mass.

With this new case, we aim to provide an overview of the existing literature and present a tool with relevant markers for the pathologist in the differential diagnosis. A 92-year-old multiparous, Caucasian woman presented with a 8 cm spherical tumor of the left major labium. Since the initial punch biopsy was not conclusive, a local resection was performed. Histopathological examination showed mucus production, large pools of mucin with trabeculae and cribriform glandular structures with strongly atypical columnar epithelium. Additional immunohistochemical analysis demonstrated expression of: CEA, CK7, EMA, and the neuroendocrine markers synaptophysin and chromogranin supporting the diagnosis. In this report, we present a new case of a mucinous adenocarcinoma of the vulva with neuroendocrine differentiation based immunohistochemical analysis. Due to the indolent tumor behavior, partial vulvectomy is the therapy of choice. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Second harmonic generation (SHG) imaging has emerged in recent years as an important laboratory imaging technique since it can provide unique structural information with submicron resolution. It enjoys the benefits of non-invasive interaction establishing this imaging modality as ideal for in vivo investigation of tissue architectures. In this study we present, polarization dependant high resolution SHG images of Caenorhabditis elegans muscles in vivo. We imaged a variety of muscular structures such as body walls, pharynx and vulva. By fitting the experimental data into a cylindrical symmetry spatial model we mapped the corresponding signal distribution of the χ (2) tensor and identified its main axis orientation for different sarcomeres of the earth worm. The cylindrical symmetry was considered to arise from the thick filaments architecture of the inside active volume. Moreover, our theoretical analysis allowed calculating the mean orientation of harmonophores (myosin helical pitch). Ultimately, we recorded and analysed vulvae muscle dynamics, where SHG signal decreased during in vivo contraction.

    A spectrum of invasive adenocarcinomas presumably arising from the anogenital mammary-like glands of the vulva has been reported. Even rarer are the cases of pure ductal carcinoma in situ that originated from these unique glandular structures. Herein, we report an 81-yr-old woman presented with an invasive well-differentiated squamous cell carcinoma of the vulva. Unexpectedly, the underlying dermis demonstrated a cystically dilated structure that displayed a layer of malignant squamous cells in the periphery, and a second centrally located population of neoplastic cells exhibiting glandular differentiation. In addition, a spindle and pleomorphic malignant cell population consistent with a sarcomatoid carcinoma was identified around the cystic structure. Scattered benign anogenital mammary-like glands were present in the adjacent dermis. The histologic and immunohistochemical findings were consistent with those of vulvar squamous cell carcinoma that has undergone sarcomatoid transformation after spreading in a pagetoid fashion into an underlying focus of ductal carcinoma in situ of anogenital mammary-like gland origin.

    The presence of accessory breast tissue such as extra nipples (polythelia) and extra breast (polymastia) is relatively common, with a high incidence of being misdiagnosed in clinical medicine. Although polythelia is congenital in origin and is identifiable at childhood, polymastia may not be evident until the influence of sex hormones during puberty. In this article, we present a review of the literature concerning the historical background of accessory breasts, their incidence, their misdiagnoses, and their association with other syndromes and diseases. Finally, we present the common treatment options available today for such conditions.

    Background Data on survival with mucosal melanoma and on prognostic factors of are scarce. It is still unclear if the disease course allows for mucosal melanoma to be treated as primary cutaneous melanoma or if differences in overall survival patterns require adapted therapeutic approaches. Furthermore, this investigation is the first to present 10-year survival rates for mucosal melanomas of different anatomical localizations. Methodology 116 cases from Sep 10 1984 until Feb 15 2011 retrieved from the Comprehensive Cancer Center and of the Central Register of the German Dermatologic Society databases in Tübingen were included in our analysis. We recorded anatomical location and tumor thickness, and estimated overall survival at 2, 5 and 10 years and the mean overall survival time. Survival times were analyzed with the Kaplan-Meier method. The log-rank test was used to compare survival times by localizations and by T-stages. Principal Findings We found a median overall survival time of 80.9 months, with an overall 2-year survival of 71.7%, 5-year survival of 55.8% and 10-year survival of 38.3%. The 10-year survival rates for patients with T1, T2, T3 or T4 stage tumors were 100.0%, 77.9%, 66.3% and 10.6% respectively. 10-year survival of patients with melanomas of the vulva was 64.5% in comparison to 22.3% of patients with non-vulva mucosal melanomas. Conclusion Survival times differed significantly between patients with melanomas of the vulva compared to the rest (p = 0.0006). It also depends on T-stage at the time of diagnosis (p<0.0001).

    Adrenal insufficiency is a rare disease, but is life threatening when overlooked. Addison's disease may be an acquired form of adrenal insufficiency due to the destruction or dysfunction of the adrenal cortex. It affects both glucocorticoid and mineralocorticoid function. Main presenting symptoms of Addison's disease such as fatigue, anorexia, vomiting and convulsion often mimics central nervous system (CNS) infections. We describe a case of Addison's disease who was initially misdiagnosed as a case of meningo-encephalitis subsequently renal tubular acidosis and finally Addison's disease. Addison's disease can remain unrecognized until acute crisis and sometimes it may be misdiagnosed.

  18. The nT1 translocation separates vulval regulatory elements from the egl-18 and elt-6 GATA factor genes.

    PubMed

    Koh, Kyunghee; Bernstein, Yelena; Sundaram, Meera V

    2004-03-01

    egl-18 and elt-6 are partially redundant, adjacent genes encoding GATA factors essential for viability, seam cell development, and vulval development in Caenorhabditis elegans. The nT1 reciprocal translocation causes a strong Vulvaless phenotype, and an nT1 breakpoint was previously mapped to the left arm of LGIV, where egl-18/elt-6 are located. Here we present evidence that the nT1 vulval phenotype is due to a disruption of egl-18/elt-6 function specifically in the vulva. egl-18 mutations do not complement nT1 for vulval defects, and the nT1 breakpoint on LGIV is located within approximately 800 bp upstream of a potential transcriptional start site of egl-18. In addition, we have identified a approximately 350-bp cis-regulatory region sufficient for vulval expression just upstream of the nT1 breakpoint. By examining the fusion state and division patterns of the cells in the developing vulva of nT1 mutants, we demonstrate that egl-18/elt-6 prevent fusion and promote cell proliferation at multiple steps of vulval development.

    Introduction. Although pyogenic granulomas (PG) are common and benign vascular proliferations of the skin and mucous membranes, they are relatively rare on the vulva. Case Presentation. A 57-year-old G7P7 postmenopausal woman presented with a 3-year history of a foul smell and bleeding lesions in the genital region. A gynecologic examination revealed multiple large papillomatous, pedunculated, and lobulated lesions that were cherry-red and infective in appearance. There was a 2-cm lesion at the upper intersection of the labia majora, a 2-cm lesion on the right labium majus, and a 4-cm lesion on the clitoris. The patient complained of itching, and the lesions were asymptomatic, except for occasional bleeding. All lesions were excised and sent for histopathological examination, which revealed an ulcerated polypoidal structure with extensive proliferation of vascular channels lined by a single layer of endothelium. The histopathological features were consistent with PG. Conclusion. The present case is the first case of multiple pyogenic granulomas on the vulva in a postmenopausal woman. PMID:21912553

    Women use various feminine hygiene products, often as part of their daily cleansing routine; however, there is a paucity of published medical literature related to the external vulva and how personal hygiene practices can affect it. This review article provides background information on the physiological changes that occur during women's lives and reviews the relevance of transient and resident microbiota as they relate to common vaginal and vulvar disorders. It also discusses the need for female intimate hygiene, common practices of feminine hygiene from a global perspective, and the potential benefits of using suitable external, topical feminine vulvar washes to minimize the risk of vulvovaginal disorders and to improve overall intimate health in women around the world. Supported by international guidelines, daily gentle cleansing of the vulva is an important aspect of feminine hygiene and overall intimate health. Women should be encouraged to choose a carefully formulated and clinically tested external wash that provides targeted antimicrobial and other health benefits without negatively impacting on the natural vulvovaginal microbiota.

    Verrucous carcinoma is a rare form of vulvar squamous carcinoma, with particular clinical presentation and histological description. We analyze the specificity of the treatment of this form. We analyzed the records of 8 patients treated in our hospital between 1995 and 2001. In the absence of an associated lesion, the treatment was partial vulvectomy without lymph node dissection. A close follow-up was then organized. Mean age was 76 years (range 54 to 92). In 7 out of the 8 cases we found an associated lesion: invasive squamous carcinoma, VIN III or lichen. Two patients later developed a squamous carcinoma. Two others died because of intercurrent diseases. The last four patients are doing well. We confirm the efficacy of the treatment generally proposed: partial vulvectomy, without lymph node dissection and without complementary treatment but with a close follow-up. The coexistence of other vulvar lesions such as lichen is remarkable in our series.

  2. Challenge in pathologic diagnosis of Alport syndrome: evidence from correction of previous misdiagnosis

    PubMed Central

    2012-01-01

    Background Pathologic studies play an important role in evaluating patients with Alport syndrome besides genotyping. Difficulties still exist in diagnosing Alport syndrome (AS), and misdiagnosis is a not-so-rare event, even in adult patient evaluated with renal biopsy. Methods We used nested case–control study to investigate 52 patients previously misdiagnosed and 52 patients initially diagnosed in the China Alport Syndrome Treatments and Outcomes Registry e-system. Results We found mesangial proliferative glomerulonephritis (MsPGN, 26.9%) and focal and segmental glomerulosclerosis (FSGS, 19.2%) were the most common misdiagnosis. FSGS was the most frequent misdiagnosis in female X-linked AS (fXLAS) patients (34.8%), and MsPGN in male X-linked AS (mXLAS) patients (41.2%). Previous misdiagnosed mXLAS patients (13/17, 76.5%) and autosomal recessive AS (ARAS) patients (8/12, 66.7%) were corrected after a second renal biopsy. While misdiagnosed fXLAS patients (18/23, 78.3%) were corrected after a family member diagnosed (34.8%) or after rechecking electronic microscopy and/or collagen-IV alpha-chains immunofluresence study (COL-IF) (43.5%) during follow-up. With COL-IF as an additional criterion for AS diagnosis, we found that patients with less than 3 criteria reached have increased risk of misdiagnosis (3.29-fold for all misdiagnosed AS patients and 3.90-fold for fXLAS patients). Conclusion We emphasize timely and careful study of electronic microscopy and COL-IF in pathologic evaluation of AS patients. With renal and/or skin COL-IF as additional criterion, 3 diagnosis criteria reached are the cutoff for diagnosing AS pathologically. PMID:23259488

    Misdiagnoses of racial/ethnic minority youth’s mental health problems can potentially contribute to inappropriate mental health care. Therefore, we conducted a systematic review that focuses on current theory and empirical research in an attempt to answer the following two questions: 1) What evidence exists that supports or contradicts the idea that racial/ethnic minority youth’s mental health problems are misdiagnosed? 2) What are the sources of misdiagnoses? Articles were reviewed from 1967 to 2014 using PsychINFO, PubMed, and GoogleScholar. Search terms included “race”, “ethnicity”, “minority”, “culture”, “children”, “youth”, “adolescents”, “mental health”, “psychopathology”, “diagnosis”, “misdiagnosis”, “miscategorization”, “underdiagnosis”, and “overdiagnosis”. Seventy-two articles and book chapters met criteria and were included in this review. Overall, evidence was found that supports the possibility of misdiagnosis of ethnic minority youth’s emotional and behavioral problems. However, the evidence is limited such that it cannot be determined whether racial/ethnic differences are due to differences in psychopathology, mental health biases, and/or inaccurate diagnoses. Cultural and contextual factors that may influence misdiagnosis as well as recommendations for research and practice are discussed. PMID:27346929

    Vaginal calculi are rarely encountered and are often misdiagnosed as bladder calculi because of the difficulty in achieving an appropriate diagnosis. Most vaginal calculi result from the presence of a urethrovaginal fistula; those occurring in the absence of such fistulas are extremely rare. We present a case of a 42-year-old bedridden woman with mental and physical disabilities who had been misdiagnosed for a decade as having a bladder calculus. We removed the calculus nonsurgically and the analyzed the components. Results demonstrated the presence of a primary vaginal calculus. Vaginal calculi may occasionally occur in disabled women, but further investigation of the etiology of such calculi is required.

    Granulocytic sarcoma (GS) of the breast is extremely rare in patients with acute myeloid leukemia (AML) and therefore, is often misdiagnosed as lymphoma or other benign tumors. The current report presents two cases of GS of the breast, of which, one was considered to be a fibroma, as observed by fine-needle aspiration, and the other was misdiagnosed as lymphoma by frozen section. Previous literature that described the clinical and pathological characteristics, treatments and prognosis of GS of the breast in AML were reviewed. In addition to the treatment of mastectomy with/without radiotherapy, lumpectomy may also be received as a good treatment plan. PMID:24348837

    Isolated agenesis of the gallbladder is a rare anomaly, often asymptomatic. However, one patient out of four presented with right upper abdominal pain, nausea, and fatty food intolerance. The condition is frequently mistaken with an excluded or sclero-atrophic gallbladder, regardless of the imaging modality used. Consequently, AG often leads to unnecessary and potentially dangerous laparoscopic surgery as described in a few case reports over the last 10 years. The aim of this study is to clarify the diagnostic and therapeutic approach of this unusual pathology. Two cases seen in our institutions were retrospectively reviewed, together with a review of the American and European literature. During laparoscopy, the absence of normal anatomical structures and the impossibility of pulling on the gallbladder to expose and dissect the triangle of Callot increases the risk of iatrogenic injury to biliary or portal structures. Depending on the experiment of the surgeon in laparoscopic procedure, this has to be taken into account to decide a conversion to laparotomy. A high index of suspicion is necessary when interpreting the radiological images. In case of doubt, a MRI-cholangiography is mandatory. Because of possible inherited transmission, relatives with a history of biliary symptoms should be investigated. PMID:16273658

    Myofascial pain syndrome (MPS) is a very common localized--sometimes also polytopic--painful musculoskeletal condition associated with trigger points, for which, however, diagnostic criteria established in well-designed studies are still lacking. These two facts form the basis for differentiating between MPS and the fibromyalgia syndrome. The difference between trigger points (MPS) and tender points (fibromyalgia) is of central importance--not merely in a linguistic sense. A knowledge of the signs and symptoms typically associated with a trigger point often obviates the need for time-consuming and expensive technical diagnostic measures. The assumption that many cases of unspecific complaints affecting the musculoskeletal system may be ascribed to MPS makes clear the scope for the saving of costs.

    Congenital chloride diarrhea (CCD) is a rare autosomal recessive disease which is characterized by intractable diarrhea of infancy, failure to thrive, high fecal chloride, hypochloremia, hypokalemia, hyponatremia and metabolic alkalosis. In this case report, we present the first female and the second official case of CCD in Iran. A 15-month-old girl referred to our hospital due to failure to thrive and poor feeding. She had normal kidneys, liver and spleen. Treating her with Shohl's solution, thiazide and zinc sulfate did not result in weight gain. Consequently, pseudo-Bartter syndrome was suspected, she was treated with intravenous (IV) therapy to which she responded dramatically. In addition, hypokalemia resolved quickly. Since this does not usually happen in patients with the pseudo-Bartter syndrome, stool tests were performed. Abnormal level of chloride in stool suggested CCD and she was thus treated with IV fluid replacement, Total parentral nutrition and high dose of oral omeprazole (3 mg/kg/day). She gained 1 kg of weight and is doing fine until present. CCD is a rare hereditary cause of intractable diarrhea of infancy. It should be considered in infants with unknown severe electrolyte disturbances.

    Primary benign tumors of trachea are rare. Of them, tracheal leiomyoma, constitutes only 1% of all benign lower respiratory tract tumors. Here, we present a case of tracheal leiomyoma who has been receiving high doses of inhaled corticosteroids and bronchodilators for a year with a misdiagnosis of asthma. As the symptoms did not resolve with an overtreatment, she has been undergone radiologic study to find a possible alternative diagnosis. The chest roentgenogram revealed an opacity in the upper mediastinum. In computed tomography, a lesion has been detected in proximal trachea, arising from the posterior wall and protruding through the lumen and almost obliterating the air column. Rigid bronchoscopy has been performed under general anesthesia due to a high risk of bleeding and the endobronchial lesion, freely moving with respiration, has been removed and cryotherapy was applied to the base of the lesion. Receiving the histopathological diagnosis of leiomyoma, the patient is now on 12th month of the follow-up without any recurrence.

The vascular anomaly in the face then grew rapidly during the first few weeks of life and started to occlude the left eye, causing parental concerns about the infant's vision. A dermatological opinion established that the lesion was a segmental infantile haemangioma (IH). This, in combination with the posterior fossa malformation previously detected on antenatal scanning and confirmed by an MRI postnatally, satisfied the criteria for Posterior fossa abnormalities, Haemangiomas, Arterial abnormalities, Cardiac abnormalities and Eye abnormalities (PHACE) syndrome: a rare cutaneous neurovascular syndrome. This case highlights the diagnostic challenge posed by early phenotypes of haemangiomas as well as the importance of correctly diagnosing PHACE syndrome. PMID:26177999

    1990-06-01

    Dystrophia myotonica (Steinert's disease) is the most common hereditary disease of the neuromuscular system in adults. Its mode of inheritance is autosomal dominant. The gene responsible for its is located on chromosome 19 in the linkage domain of the loci for the apolipoproteins C2, C1 und E and of the creatine kinase of skeletal muscle (CKMM). Myotonic dystrophy is categorized in an adult and in a congenital form. In the adult form, the characteristic findings are muscular atrophy in certain regions of the body (face, neck and distally in the extremities) and myotonia. Cataract, intraocular hypotension, gonadal atrophy, conduction abnormalities in the heart and hearing deficiencies appear quite often in the course of the disease. In the congenital form, general muscle weekness (particularly pronounced in the face) is the leading finding, combined with retarded loco motor and mental development. A decisive criterion for the diagnosis of this form is the occurrence of myotonic dystrophy in the patient's mother. Electromyographic investigation is indicated when a suspicion of myotonic dystrophy cannot be ascertained on the basis of clinical and genetic findings. Myotonic runs in the EMG will then corroborate the suspicion. Recent electrophysiological investigations have indicated that at least three different types of channels for the passage of ions through the membrane of the skeletal muscle cells show abnormal behaviour, i.e. the channel for Cl-, Na+ and K+. These findings corroborate the hypothesis that the abnormality responsible for myotonic dystrophy is situated in the membrane systems. A pharmacological treatment of the muscular dystrophy has not yet been developed.(ABSTRACT TRUNCATED AT 250 WORDS)

    For more than a decade, risk stratification for hypertrophic cardiomyopathy has been enhanced by targeted genetic testing. Using sequencing results, clinicians routinely assess the risk of hypertrophic cardiomyopathy in a patient's relatives and diagnose the condition in patients who have ambiguous clinical presentations. However, the benefits of genetic testing come with the risk that variants may be misclassified. Using publicly accessible exome data, we identified variants that have previously been considered causal in hypertrophic cardiomyopathy and that are overrepresented in the general population. We studied these variants in diverse populations and reevaluated their initial ascertainments in the medical literature. We reviewed patient records at a leading genetic-testing laboratory for occurrences of these variants during the near-decade-long history of the laboratory. Multiple patients, all of whom were of African or unspecified ancestry, received positive reports, with variants misclassified as pathogenic on the basis of the understanding at the time of testing. Subsequently, all reported variants were recategorized as benign. The mutations that were most common in the general population were significantly more common among black Americans than among white Americans (P<0.001). Simulations showed that the inclusion of even small numbers of black Americans in control cohorts probably would have prevented these misclassifications. We identified methodologic shortcomings that contributed to these errors in the medical literature. The misclassification of benign variants as pathogenic that we found in our study shows the need for sequencing the genomes of diverse populations, both in asymptomatic controls and the tested patient population. These results expand on current guidelines, which recommend the use of ancestry-matched controls to interpret variants. As additional populations of different ancestry backgrounds are sequenced, we expect variant reclassifications to increase, particularly for ancestry groups that have historically been less well studied.

    A previously healthy 24-year-old man presented with an erythematous, non-pruritic and painless papulonodular skin rash affecting the trunk, upper arms (excluding palms), neck, face, forehead and scalp. He had a penile ulcer for the past 2 weeks, almost healed at the time of observation. The patient tested positive for syphilis and HIV-1; he claimed being negative for HIV 6 months earlier. As the palms were not affected, we performed a skin biopsy for the differential diagnosis between secondary lues and acute HIV seroconversion reaction. Benzathine penicillin (2 400 000 units) was administrated and antiretroviral therapy started. Although the skin biopsy was compatible with secondary syphilis, there was no change in the skin rash 3 weeks after the first penicillin administration. Another 2 doses of penicillin were given but 4 weeks later the rash persisted. A second biopsy revealed a mucinous skin infiltration, compatible with nodular mucinosis. PMID:26311009

    We investigated the sero-prevalence of toxocariasis among healthy Korean adults in 1999. A total of 314 sera from normal inhabitants in Whachon-gun, Gangwon-do, Korea was examined for specific antibody levels against excretory-secretory products of second stage larvae of Toxocara (TES). The presence of cross-reactions with other helminthiases such as cysticercosis, paragonimiasis, sparganosis or clonorchiasis was also checked by specific IgG ELISA. Sera showing positive reaction against TES were also tested by IgG immunoblot and by IgE ELISA. Out of 314 subjects, 16 was found to be positive by TES IgG ELISA and immunoblot, among whom 12 were also positive by TES IgE ELISA. Among the 16 seropositive samples, two sera showed positive reaction against Paragonimus and sparganum antigen, respectively. These results inferred that cross-reactions were negligible between toxocariasis and other helminthiases. Toxocariasis seroprevalence among Korean rural adults was detected to be approximately 5%.

    In the 21st century, despite increased international travel for vacation, work, and medical missions and immigration into the United States, there is little published in the dermatology literature regarding the cutaneous manifestations of helminth infections. It has been estimated that 20% to 70% of international travelers suffer from some travel-related health problem. Approximately 17% of travelers seek medical care because of cutaneous disorders, many related to infectious etiologies. This review will focus on cutaneous diseases caused by helminth infections. Part I of the review focused on nematode infections; part II will focus on trematode and cestode infections. Nematodes are roundworms that cause diseases with cutaneous manifestations, such as cutaneous larval migrans, onchocerciasis, filariasis, gnathostomiasis, loiasis, dracunculiasis, strongyloidiasis, ascariasis, streptocerciasis, dirofilariasis, and trichinosis. Tremadotes, also known as flukes, cause schistosomiasis, paragonimiasis, and fascioliasis. Cestodes (tapeworms) are flat, hermaphroditic parasites that cause diseases such as sparganosis, cysticercosis, and echinococcus. Copyright © 2014 American Academy of Dermatology, Inc.

    Thirty-seven unusual specimens, three from Ethiopia and 34 from South Sudan, were submitted since 2012 for further identification by the Ethiopian Dracunculiasis Eradication Program (EDEP) and the South Sudan Guinea Worm Eradication Program (SSGWEP), respectively. Although the majority of specimens emerged from sores or breaks in the skin, there was concern that they did not represent bona fide cases of Dracunculus medinensis and that they needed detailed examination and identification as provided by the World Health Organization Collaborating Center (WHO CC) at Centers for Disease Control and Prevention (CDC). All 37 specimens were identified on microscopic study as larval tapeworms of the spargana type, and DNA sequence analysis of seven confirmed the identification of Spirometra sp. Age of cases ranged between 7 and 70 years (mean 25 years); 21 (57%) patients were male and 16 were female. The presence of spargana in open skin lesions is somewhat atypical, but does confirm the fact that populations living in these remote areas are either ingesting infected copepods in unsafe drinking water or, more likely, eating poorly cooked paratenic hosts harboring the parasite.

To investigate the diagnostic condition of TIO in China and raise clinicians' awareness of TIO, we retrospectively analyzed clinical manifestations, biochemical features, and specially evaluated missed diagnoses and misdiagnoses among 144 TIO patients from Peking Union Medical College Hospital during December 1982 to December 2014. Clinical presentations of TIO mainly included bone pain, difficulty in walking, pathological fractures, muscle weakness, and height loss. TIO patients demonstrated hypophosphatemia (0.48±0.13 mmol/L), elevated serum alkaline phosphatase (277.9±152.6 U/L), reduced tubular maximum for phosphorus/glomerular filtration rate (0.39±0.14) and markedly elevated serum fibroblast growth factor 23 (FGF23) (median level 302.9 pg/mL). The average time from onset to a correct diagnosis was 2.9±2.3 years while the mean duration from onset to tumor resection was 5.4±4.2 years. The initial misdiagnosis rate was 95.1% (137/144) and 240 case-times of misdiagnoses occurred among the 144 cases. The most frequent misdiagnoses were intervertebral disc herniation, spondyloarthritis (including ankylosing spondylitis) and osteoporosis. A total of 43.1% (62/144) cases with hypophosphatemia presented on their laboratory sheets were neglected and missed diagnosed. Our study showed that TIO was frequently misdiagnosed and missed diagnosed due to its rarity, insidious onset, nonspecific clinical manifestations and clinicians' poor recognition. It is necessary to test serum phosphorus in patients with musculoskeletal symptoms and difficulty in walking. The measurement of serum FGF23 is rather valuable. Once hypophosphatemia is discovered, TIO should be suspected and it is highly recommended to search for tumors and perform curative surgery.

    Early-stage cerebellar hemorrhage can present with nausea or vomiting absent other neurological symptoms or signs, potentially leading to an incorrect diagnosis of gastroenteritis. We sought to determine the frequency of gastroenteritis-like presentations and delayed or missed diagnoses among patients with spontaneous cerebellar hemorrhage. This is a retrospective, case-control analysis of atraumatic, primary cerebellar hemorrhages derived from a systematic search of surgical pathology and autopsy databases at two large urban, academic medical centers from 1984 to 2006. Hospital visit and clinical symptom data were abstracted from electronic and paper medical records for included patients. Delayed or missed diagnoses were defined as those at least one previous visit for relevant clinical symptoms in the 7 days prior to the correct diagnosis being confirmed. Among 254 records captured by our search filter, we identified 35 cases of pathologically proven primary cerebellar hemorrhage. Four patients (11%) were misdiagnosed initially - three with "gastroenteritis" and one with "hypertension". In this small sample, misdiagnosed patients presented more often with normal mental state (100% vs. 35%, p=0.07) and nausea/vomiting (100% vs. 58%, p=0.22). Although patients deteriorated clinically after the initial misdiagnosis, and potentially dangerous diagnostic tests and treatment strategies were instituted as a result of misdiagnosis, none of the misdiagnosed patients died or suffered major permanent harms due to diagnostic delay. Our study is limited by the small number of identified cases. Nevertheless, it appears that patients with cerebellar hemorrhages can present with relatively unimpressive clinical findings without obvious neurological manifestations. Such individuals are sometimes misdiagnosed with gastroenteritis or other benign disorders initially, possibly when neurologic examination, particularly gait testing, is omitted or abridged.

    Lymphangiomatous polyps of the palatine tonsils are uncommon hamartomatous proliferations that could be clinically misdiagnosed as malignant neoplasms. These polyps consist of dilated lymphatic vessels located inside fibrous and/or adipose tissue. In this paper, a 27-year-old man who presented to the outpatient clinic with a complaint of dysphagia is presented. On physical examination, the patient had a smooth, polypoid mass extending from the posterior section of the right palatine tonsil into the oropharynx. The patient underwent right tonsillectomy. Histopathological examination of the specimen showed typical features of a lymphangiomatous polyp of the tonsil. The case is reported with the accompanying literature to avoid the possibility of misdiagnosing it as a malignant lesion clinically.

    Ruptured pulmonary hydatid cyst (PHC) is an important clinical problem in endemic areas to echinococcal infection. Herein we present a rare case of ruptured PHC in an adolescent boy that was misdiagnosed as pulmonary tuberculosis in local health center. When sputum specimen was stained by acid-fast staining for detection of Mycobacterium tuberculosis, hooklets of Echinococcus granulosus were observed. A simple chest X-ray showed a multilobulated mass in the lower part of the left lung. Computed tomography scan verified existence of thick walled caviar lesion with irregular air-fluid level. The diagnosis was confirmed at the time of surgery. Misdiagnoses of PHC may even lead to irreparable damages. Therefore, accurate diagnosis is necessary to prevent severe complications.

    ABSTRACT: Narcolepsy is an uncommon sleep cycle disorder with a usual onset in adolescence, but it is often misdiagnosed and underdiagnosed. Rarely is the tetrad of excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, and sleep paralysis seen in patients. The clinical characteristics of narcolepsy are often confused with many psychiatric and neurologic disorders. Lack of clinical awareness about narcolepsy leads to frequent prescriptions of antiepileptics and psychotropics, which can adversely affect the quality of life of children and adolescents. We report a case of an adolescent male who presented with all four cardinal symptoms of narcolepsy and had been misdiagnosed with epilepsy, psychosis, and depression. We discuss various issues regarding narcolepsy in children and adolescents. PMID:29616151

    As part of a faunistic study on helminth parasites of Iranian lizards collected from localities in the north of Isfahan province in Iran, two new nematode species belonging to two different families, Pharyngodonidae Travassos, 1919 and Physalopteroidae Railliet, 1893, were found and are, hereby, described. Spauligodon persiensis n. sp. from the large intestine of Cyrtopodion scabrum Heyden is characterised by its imperceptible lateral alae, lack of spicule, different shape of the genital curtain, position of last pair of papillae, aspinose tail in males, position of the vulva and excretory pore, and a tail filament with six to nine spines in females. Thubunea mobedii n. sp. from the stomach of Laudakia nupta nupta (De Filipi) differs from the other species in the genus by possessing a vulva at level of the posterior portion of the oesophageal-intestinal junction in females, lacking spicules, and having a different number of papillae in males. The present paper provides the results of detailed morphological examination of the two new nematode species, using both light and scanning electron microscopy. Taxonomically important characteristics for the members of the two nematode genera, Spauligodon Skrjabin, Schikhobalova & Lagodovskaja, 1960 and Thubunea Seurat, 1914, are also reviewed.

    According to various statistics from 4.2 to 42% of women in reproductive age, complained of a mild or severe problems in sexual function. The study presents own data on treatment of vaginismus in 14 girls and young women aged 16 to 36 years who have turned from 2007 to 2012 to the Cabinet Children and adolescent gynaecology at the University Hospital "Maychin dom". A primary examination established a high and tenacious hymen in 7 (50%) patients. The patients demonstrated fear, but still allowed careful examination. At 3 girls (21.43%) a combined cause of complaints was found. They demonstrated fear of pain during coitus and reported bad memory of the first sexual attempts; they had high and tenacious hymen and were able to tolerate touching the vulva after much persusions. In 3 (21.43%) patients consequences of puritan education were registered. They did not allowed to touch the vulva despite the declaration that would allow such. In one patients (7.14%) a unstretchable vagina was found. She demonstrated dyspareunia (avoiding intercourse and having one failed marriage) but she tolerated penetration of her vagina of one phalanx. In all cases of vaginismus we performed educational lectures and artefitial defloration.

    Genital human papillomavirus (HPV) infections are very common in women 18 to 30 years old and substantially affect women's sexual health. To examine sexual activity, psychosexual distress, and fear of progression in women diagnosed with HPV-related precancerous genital lesions. In this observational study, women diagnosed with premalignant lesions of the cervix, vagina, or vulva were recruited from a university hospital-based colposcopy clinic. Quantitative data from three validated patient-administered questionnaires (Sexual Activity Questionnaire, German version of the Cervical Dysplasia Distress Questionnaire, and Fear of Progression Questionnaire) were compared within the study population, according to the location of the genital lesion, and with relevant reference populations. Qualitative data from two written open-ended questions about women's thoughts regarding diagnosis and information were analyzed. Two-hundred nine women completed the questionnaires. Seventy-eight percent of women (n = 162) were referred for evaluation of suspect lesions of the cervix, 8% (n = 17) of the vagina, and 14% (n = 30) of the vulva. There were no significant differences in questionnaire results among the three patient groups, except for sexual consequences (Cervical Dysplasia Distress Questionnaire) and recent sexual activity (Sexual Activity Questionnaire). Women with vulvar lesions were most likely to worry about sexual consequences (ie, being unable to have children, being sexually less attractive, or infecting a sexual partner; P = .04). The Sexual Activity Questionnaire subscales sexual pleasure (P = .15) and sexual habits (P = 1.00) were similar to those in a healthy control population, whereas sexual discomfort (P = .51) was comparable to that in a reference population of women who survived cervical cancer. The subscale partner-specific concerns (Fear of Progression Questionnaire) was similar to that in a reference population of patients with cancer (P = .28). HPV

    The extent of the receptive period may determine the mating strategies employed by female crabs to obtain mates. Here, we studied the receptivity of female Neohelice granulata (Dana, 1851) in the laboratory, including the form of the vulvae and the anatomy of the seminal receptacle (SR). We examined the factors that influence the duration of receptivity by comparing two populations inhabiting contrasting habitats: Mar Chiquita Coastal lagoon (MCL), which is an oligo-polyhaline estuary, and San Antonio Oeste (SAO), which is an eu-hyperhaline marine bay. Non-receptive females have immobile vulva opercula, while receptive females have mobile opercula. Histological sections of the SR showed that the degree of epithelium secretions was associated with the receptive stage of females, and they may be involved in the maintenance of viable sperm and in the dehiscence of spermatophores. The existence of a special tissue at the junction of the oviduct and the SR was described and proposed as an internal mechanism influencing the timing of ovulation. The duration of receptivity was dependent on the SR load and the capacity to lay eggs. Thus, females with empty SR exhibited longer receptivity and did not lay eggs, while those with full SR exhibited shorter receptivity and always laid eggs. Interpopulation differences showed that females from SAO had shorter receptivity and heavier SR and laid eggs more frequently than females from MCL. Based on our results, we suggest that N. granulata females can adjust the duration of their receptivity and control the moment of fertilization according to different internal mechanisms related to the morphology of the vulvae, the fullness of the SR and anatomical attributes of the SR. An important consequence of this control is greater sperm competition. The extent of the receptive period and the number of times that a female could become receptive in a single reproductive season may also depend on the habitat characteristics.

    Summary Sesamoid bones and accessory ossicles are research focuses of foot and ankle surgery. Pains of the foot and ankle are related to sesamoid bones and accessory ossicles. The specific anatomical and functional relationship of sesamoid bones and accessory ossicles can cause such bone diseases as the dislocation of sesamoid bones and accessory bones, infection, inflammation and necrosis of sesamoid bones, cartilage softening, tenosynovitis of sesamoid bones and the sesamoid bone syndrome. However, these bone diseases are often misdiagnosed or mistreated. In patients with trauma history, relevant diseases of sesamoid bones and accessory ossicles as above mentioned are highly probable to be misdiagnosed as avulsion fractures. In such cases, radiographic findings may provide a basis for clinical diagnosis. PMID:25343083

    First branchial cleft anomalies are a very rare entities accounting for less than 1 % of all branchial cleft malformations. They are often misdiagnosed for other cystic lesions occurring in parotid gland and inadequately treated (incision and drainage or incomplete excision) leading to multiple recurrences. We report a series of four patients who were previously operated (incision and drainage) for misdiagnosed first branchial cleft anomalies with subsequent recurrences. All patients underwent superficial parotidectomy with complete tract excision using facial nerve monitoring to prevent iatrogenic injury because of extensive fibrosis. We discuss the literature pertaining to first branchial cleft anomalies, their varied presentations and their relationship to facial nerve in parotid gland and importance of facial nerve monitoring in revision surgery.

    Huntington's disease (HD) is an inherited, progressive, and neurodegenerative neuropsychiatric disorder caused by the expansion of cytosine-adenine-guanine (CAG) trinucleotide in Interested Transcript (IT) 15 gene on chromosome 4. This pathology typically presents in individuals aged between 30 and 50 years and the age of onset is inversely correlated with the length of the CAG repeat expansion. It is characterized by chorea, cognitive deficits, and psychiatric symptoms. Usually the psychiatric disorders precede motor and cognitive impairment, Major Depressive Disorder and anxiety disorders being the most common presentations. We present a clinical case of a 65-year-old woman admitted to our Psychiatric Acute Unit. During the 6 years preceding the admission, the patient had clinical assessments made several times by different specialties that focused only on isolated symptoms, disregarding the syndrome as a whole. In the course of her last admission, the patient was referred to our Neuropsychiatric Team, which made the provisional diagnosis of late-onset Huntington's disease, later confirmed by genetic testing. This clinical vignette highlights the importance of a multidisciplinary approach to atypical clinical presentations and raises awareness for the relevance of investigating carefully motor symptoms in psychiatric patients.

    This is the case of a 25-year-old African American woman with a 3-week history of itching with burning, blistering lesions on her torso and extremities. Medical history was unremarkable. Medical treatments included three visits to urgent care, where she was treated with antivirals, oral and topical steroids, antibiotics and antifungals unsuccessfully. We performed a skin biopsy, and immunoflorescent studies revealed a linear deposition of IgA antigen at the basement membrane. The clinical diagnosis of linear IgA dermatosis (LAD) was established, with no eliciting cause, other than potential occupational exposure to Chlamydophila psittaci via her employment in a pet store. This is the first case to our knowledge to report such an association. However, confirmation of the exposure would only establish correlation, not causality. Resolution of symptoms and blisters was achieved with dapsone treatment. Accordingly, we highlight the crucial importance of reviewing exposures, along with the potential aetiology of LAD. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Functional constipation is one of the common problems in childhood, and it comprises approximately 5% of the pediatric outpatient clinical applications. On the other hand, celiac disease (CD) is an immune enteropathy with the prevalence between 1/150 and 1/200. In addition to the classical symptoms of the disease such as diarrhea and weight loss, the incidence of atypical symptoms is increasing. This study aims to determine the prevalence of CD in patients with chronic constipation. The study was conducted between 2010 and 2012 and included 1046 children (range, 2-18 y; median, 11.4 y) diagnosed with chronic constipation according to the Rome III criteria. Serum immunoglobulin A, tissue transglutaminase, and/or anti-endomysial antibodies were examined. The patients with serological positive results were subjected to upper gastrointestinal system endoscopy and duodenal biopsy to confirm the diagnosis of CD. Blood tests were positive in 36 patients (3.25%). One of the patients had Hashimoto's thyroiditis, and 4 patients had short stature. Endoscopic findings included nodularity in bulbus and duodenal mucosa (n=16), scalloping fold (n=13), and normal mucosa (n=5). Histopathologic findings revealed that 10 patients had total villous atrophy, 24 patients had subtotal and partial villous atrophy, and 34 patients had intraepithelial lymphocyte infiltration. All patients followed a gluten-free diet, resulting in a resolution of symptoms. In the present study, a CD ratio of 1:28 was diagnosed in chronically constipated children. The use of screening tests for CD should be considered in children with conventional treatment-resistant constipation.

    The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool. In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients ≥18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain. Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n = 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar. A clinically relevant portion of patients previously diagnosed with functional abdominal pain syndrome in a primary care environment suffers from an abdominal wall pain syndrome such as ACNES.

    Granular cell tumors (GCTs) are rare soft tissue neoplasms which may be multicentric. The vast majority are benign, however approximately 100 malignant GCTs have been reported, with only 8 originating in the vulva. Malignant GCTs are very aggressive with very poor survival rates. As the diagnosis of malignant GCT carries an extremely poor prognosis, the utilization of EM ensures that the most accurate diagnosis possible can be rendered.

Ten years previously the patient had been treated for squamous cell carcinoma of the cervix. Although lymphangioma circumscriptum is an extremely rare complication of altered lymphatic drainage, the presence of multiple noninflammatory vesicular appearing lesions in this setting should suggest the correct diagnosis.

    Since 1984, perineal template/needle techniques for interstitial implantation of gynecologic cancer-cervix, vagina, vulva-have been developed at the Peter MacCallum Cancer Institute. The Paris System of dosimetry has been used resulting in greater dose homogeneity, fewer needles and radioactive sources and considerable simplification and ease of implantation compared with comparable techniques developed in the United States. Principles and techniques of implantation are described in detail.

    The Morel-Lavallée lesion (MLL) is a rarely reported closed degloving injury, in which shearing forces have lead to break off subcutaneous tissues from the underlying fascia. Lumbar MLL have been rarely reported to date, explaining that patients are frequently misdiagnosed. While patients could be treated conservatively or with non-invasive procedures, delayed diagnosis may require open surgery for its cure. Indeed, untreated lesions can cause pain, infection or growing subcutaneous mass that can be confused with a soft tissue tumor. We report the clinical and radiological features of a 45-year old man with voluminous lumbar MLL initially misdiagnosed. We also reviewed the relevant English literature to summarize the diagnostic tools and the main therapeutic options. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Dermatophytosis caused by Trichophyton rubrum is the most common cutaneous fungal infection in industrialized countries and worldwide with high recurrence and lack of treatment response. In addition, patients with cutaneous and concurrent toenail lesions are often misdiagnosed and therefore treated with an inappropriate therapy. In this study, we evaluated five previously misdiagnosed cases of T.rubrum chronic dermatophytosis sustained by two variants at sites distant from the primary lesion. Our patients were successfully treated by systemic and topical therapy, and 1 year after the end of therapy follow-up did not show any recurrence of infection.Our data indicate that the localization of all lesions, the isolation and the identification of the causative fungus are essential to establish the diagnosis and the setting of a correct therapeutic treatment to avoid recurrences.

  10. True vaginal prolapse in a bitch.

    PubMed

    2007-08-01

    Frequently, vaginal fold prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during proestrus and estrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In the bitch, this type of true vaginal prolapse is a very rare condition. This short communication describes a 5-year-old female, cross-breed dog in moderate condition, weighing 33 kg, with distocia and true vaginal prolapse. Abdominal palpation and transabdominal ultrasonography revealed live and dead foetuses in the uterine horns. One dead and four live fetuses were removed from uterus by cesarean section. The ovariohysterectomy was performed after repositioning the vaginal wall with a combination of traction from within the abdomen and external manipulation through the vulva. Re-occurrence of a vaginal prolapse was not observed and the bitch recovered completely after the surgical therapy. Compared to other vaginal disorders, vaginal prolapse is an uncommon condition in the bitch. In the present case, extreme tenesmus arising from distocia may have predisposed to the vaginal prolapse. The cause of dystocia was probably the disposition of the first foetus. We concluded that the vaginal prolapse was the result of dystocia in the present case.

    A 1.5-year-old German Shepherd mixed breed dog was admitted with mild haemorrhage from the vulva and a perineal mass of 24-hour duration, which had been first observed immediately after parturition. Parturition had occurred at low ambient temperature, and only one puppy survived out of the seven oversized fetuses. The dog was in poor body condition, dehydrated, hypothermic, depressed, non-ambulatory and in a state of shock. Intestinal loops, the urinary bladder and the uterine horns and body were protruding from the vulva. A true vaginal prolapse was also observed. The abdominal viscera were flushed with warm sterile saline solution, protected and maintained wet. The laboratory findings included moderate anaemia, leukocytosis, hypoalbuminaemia, azotaemia and elevated liver enzyme activities. Stabilisation of the dog's general condition was attempted before surgery. Antimicrobial and analgesic drugs were also administered. After exploratory laparotomy the protruding organs, which were in good condition, were reduced. A recent rupture in the vaginal wall, approximately 6 cm long, was observed. Ovariohysterectomy and partial vaginectomy were performed. The preoperative course of therapy was continued, but the bitch died 12 hours later. The probable cause of vaginal rupture and evisceration in this bitch was tenesmus and/or trauma due to the oversized fetuses.

  12. Dynein-mediated trafficking negatively regulates LET-23 EGFR signaling

    Epidermal growth factor receptor (EGFR) signaling is essential for animal development, and increased signaling underlies many human cancers. Identifying the genes and cellular processes that regulate EGFR signaling in vivo will help to elucidate how this pathway can become inappropriately activated. Caenorhabditis elegans vulva development provides an in vivo model to genetically dissect EGFR signaling. Here we identified a mutation in dhc-1, the heavy chain of the cytoplasmic dynein minus end–directed microtubule motor, in a genetic screen for regulators of EGFR signaling. Despite the many cellular functions of dynein, DHC-1 is a strong negative regulator of EGFR signaling during vulva induction. DHC-1 is required in the signal-receiving cell and genetically functions upstream or in parallel to LET-23 EGFR. LET-23 EGFR accumulates in cytoplasmic foci in dhc-1 mutants, consistent with mammalian cell studies in which dynein is shown to regulate late endosome trafficking of EGFR with the Rab7 GTPase. However, we found different distributions of LET-23 EGFR foci in rab-7 versus dhc-1 mutants, suggesting that dynein functions at an earlier step of LET-23 EGFR trafficking to the lysosome than RAB-7. Our results demonstrate an in vivo role for dynein in limiting LET-23 EGFR signaling via endosomal trafficking. PMID:27654944

    Pemphigus vulgaris (PV) is an autoimmune blistering disease of the skin and mucous membranes. Genital involvement occurs when most other common sites are concurrently affected or are in remission. Systemic lupus erythematosus (SLE) is an autoimmune disease that may affect many parts of the body and the skin with occasional bullous lesions. Pemphigus vulgaris and SLE may be associated, albeit rarely. Here, we report the first case of a woman affected with SLE presenting with early invasive squamous cell carcinoma (SCC) arising from Pemphigus Vulgaris of the vulva. A 27-year-old Caucasian woman was admitted to our Gynaecology Unit for bleeding vegetant lesions of the vulva. Her history was characterized by systemic lupus erythematosus and PV. Biopsy showed concomitant PV and vulvar intraepithelial neoplasia (VIN) grade 3. One month later a new biopsy revealed progression from VIN 3 to early SCC. Despite chemotherapy, no remission of disease was observed. She died six months after diagnosis Our case underlines PV as another chronic inflammatory disease of the lower genital tract predisposing to VIN-SCC. It suggests the need for careful follow-up of patients with chronic inflammatory disease, especially when concomitant autoimmune disorders are present. Moreover, a biopsy should be always performed if there are PV lesions because of the possibility of neoplastic disease.

    The results of treatment in the department of 607 patients with invasive squamous cell carcinoma of the vulva between 1952 and 1980 is described and analyzed. The absolute 5-year cure rate in these patients was 60.3%. Particular attention was given to lymph node status (TNM system) in the analysis of the last 141 patients treated. The absolute 5-year survival rate was 67% for the N0-N1 patients and 43% for the N2-N3 patients. Patients were treated uniformly by means of electrosurgical operation and postactinic irradiation of the inguinal lymph nodes. Operative lymphadenectomy was performed only in 5% of cases when themore » diameter of inguinal lymph nodes was greater than 2 cm. This simple surgical technique, in combination with irradiation of inguinal lymph nodes, gives excellent results and avoids the complications associated with inguinofemoral lymphadenectomy. Owing to its combination of electrosurgical operation of the vulva and irradiation of the inguinal regions as a standard procedure, the treatment involves extremely low strain on the patient and is almost free of complications. This seems to be particularly important as the results of our treatment are not less satisfactory than those of more aggressive procedures.« less

    Vulvodynia (VVD) is a chronic pain disorder, wherein women display sensitivity to evoked stimuli at the vulva and/or spontaneous vulvar pain. Our previous work suggests generalized hyperalgesia in this population, however little is known about central neurobiological factors that may influence pain in VVD. Here we investigated local (vulvar) and remote (thumb) pressure evoked pain processing in 24 VVD patients compared to 13 age-matched, pain-free healthy controls (HC). As a positive control we also examined thumb pressure pain in 24 fibromyalgia (FM) patients. The VVD and FM patients displayed overlapping insular brain activations that were greater than HC, in response to thumb stimulation (P<0.005 corrected). Compared to HC, VVD participants displayed greater levels of activation during thumb stimulation within the insula, dorsal mid-cingulate, posterior cingulate and thalamus (P<0.005 corrected). Significant differences between VVD subgroups (primary versus secondary and provoked versus unprovoked) were seen within the posterior cingulate with thumb stimulation, and within the precuneus region with vulvar stimulation (provoked versus unprovoked only). The augmented brain activation in VVD patients in response to a stimulus remote from the vulva suggests central neural pathology in this disorder. Moreover, differing central activity between VVD subgroups suggests heterogeneous pathologies within this diagnosis. PMID:23578957

  19. Changes in the timing of SIDS deaths in 1989 and 1999: indirect evidence of low homicide prevalence among reported cases.

    PubMed

    Pollack, Harold A

    2006-01-01

    An unknown proportion of cases diagnosed as sudden infant death syndrome (SIDS) are misdiagnosed, and in some cases are homicides. Because recent SIDS prevention measures were unlikely to reduce homicides, changes in the reported timing of SIDS cases provide an indirect measure of covert homicides in this group. This paper uses United States vital statistics microdata to explore these questions. The sample includes all reported infant deaths to singletons with birthweight > 500 g in the 1989 and 1999 US birth cohorts. Deaths attributed to SIDS (n = 7708), homicide (n = 597), or object inhalation and mechanical suffocation (n = 860) are specifically examined. If reported SIDS cases were a mixture of 'true' cases and misdiagnosed homicides, it is hypothesised that the age-at-death distribution of SIDS deaths would have changed to reflect greater prevalence of misdiagnosed homicide. We find that the age-at-death distribution of reported SIDS cases was virtually unchanged in the two cohorts, showing no increase during periods of infancy when relative homicide risk is most pronounced. One cannot reject the hypothesis that the timing was drawn from the same distribution (chi2(52)= 62.2, P = 0.157). Analogous results hold for infants born in circumstances associated with high homicide risk (chi2(50) = 61.5, P = 0.12). The stable age-at-death distribution of reported SIDS cases between 1989 and 1999 suggests that covert homicides are a small fraction of reported SIDS cases.

    Human papillomavirus (HPV) infection of the female genital tract is a sexually transmissible disease most frequently manifested by warts on the vulva, anogenital region, vagina and cervix. Precancerous lesions of vulvar intraepithelial neoplasia (VIN) as well as the development of invasive malignant neoplasms are also related to the infections caused by some HPV types. Infections with HPV-6 and HPV-11, the disease is often polycentric, sometimes reaching gigantic dimensions, elicit venereal warts. Amongst several histological criteria for diagnosing this change, the most typical is koilocytosis, with perinuclear halo formation with a thick cytoplasmic border. Precancerous changes of the vulva and anogenital region are displastic changes of the squamous epithelium, characterized by high mitotic activity, disturbance of nucleocytoplasmic relationship and lack of differentiation in the upper epithelial layers. The changes in the epithelium divided into thirds starting from basal membrane is the main criterion in estimating the degree of dysplasia, marked by VIN 1, VIN 2 and VIN 3. According to the nuclear and cytoplasmic characteristics. VINs are subclassified into three types: basaloid, verrucous (condylomatous) and well differentiated. Basaloid and verrucous (condylomatous) VIN types are morphological markers of HPV infection. The squamous cell carcinoma of the vulva and anogenital region is a morphologically heteregenous neoplasm with particular histological entities connected with HPV infection. Four cases of patients with changes in the anogenital region in the form of small to gigantic polypoid formations were reported. The histological features corresponded to vulvar intraepithelial neoplasms (VIN lesions), as well as to neoplastic changes characteristic of HPV infection. The evolution of the changes from typical condylomas through VIN lesions to infiltrative neoplasms, taking place over the years, was also verified. Some histologically typical epithelial

    Adenomyosis is a pathological gynaecological condition characterised by benign invasion of the endometrium into the myometrium. It is often misdiagnosed, or is not easily recognised, although it is responsible for disabling symptoms such as menorrhagia, abnormal uterine bleeding, dysmenorrhoea and infertility in premenopausal women. The aim of this pictorial review is to analyse the features of adenomyosis by illustrating the most usual and typical imaging patterns, along with the unusual appearances, seen in a vast array of gynaecological imaging modalities. The different findings of focal and diffuse adenomyosis along with the diagnostic limitations of ultrasound, hysterosalpingography and magnetic resonance imaging are described, as are the pitfalls and differential diagnosis with other pathological conditions that are often misdiagnosed as adenomyosis. The role of the different imaging modalities in planning appropriate treatment and their usefulness in monitoring therapy are also discussed.

The authors describe a case of tinea faciei on the right eyebrow caused by Trichophyton interdigitale. The patient was an 18-year-old girl, who had an inflammatory plaque with a scaly, pustular surface on the right eyebrow and upper eyelid, which had persisted for over 1 month. She was once misdiagnosed as having eczema and was treated using corticosteroid cream. A diagnosis of tinea faciei was made based on direct microscopy and culture. The sequencing of the nuclear ribosomal ITS region and β-tubulin gene of the isolate established its T. interdigitale lineage. The patient was cured by treatment with systemic terbinafine in combination with topical application of 1% naftifine-0.25% ketaconazole cream for 2 weeks.

The main risk factors contributing to vaginitis are aerobic and anaerobic bacterias, fungal and viral infections, and irritants. Subjective complaints are pruritus, vulvar and/or perivulvar erytema and different in volume and characterization discharge. Excepting etiological treatment in most cases it is necessary to use additional agents, for example Saforelle.

    The slides of 64 vulvectomy specimens from vulvar squamous carcinoma were reviewed in order to study the histopathologic changes adjacent to the neoplasia. Normal epithelium was found in 7 cases (11%) and epithelial alterations adjacent to carcinoma in 59 (89%). The epithelial alterations found were: nonneoplastic epithelial disorder (NNDV) in 38 cases (59%) and vulvar intraepithelial neoplasia (VIN) in 19 (30%). The distribution of NNDV was: 20 cases of epithelial hyperplasia (EH) (31%), 6 of lichen sclerosus (9%) and 12 of the mixed type (19%). Sixteen cases of VIN 3 (25%) were undifferentiated, and three cases were differentiated VIN. Eighteen of 19 VIN cases were associated with NNDV, and 8 cases of undifferentiated VIN were associated with human papillomavirus infection. There was no apparent relationship between the associated lesions and tumor size, depth of invasion, lymph node metastases and clinical stage. Nevertheless, we found a significantly higher frequency of associated lesions in poorly differentiated tumors (P > .01). The most important finding was a high association between EH (50%) and VIN (30%) with carcinoma. VIN cases were almost always (95%) associated with EH.

    Twenty-nine samples from 28 cases of vulvar squamous cell carcinoma, of which 13 fulfilled the criteria of the bowenoid subtype (mean age 45 years, range 31-68) and 16 of the usual subtype of invasive squamous cell carcinoma (ISCC) (mean age 67.5 years, range 34-83) were investigated for human papillomavirus (HPV) DNA, TP53 alterations, and mdm2 and bcl-2 gene product deregulation. Microscopically all the bowenoid subtype cases (group I) showed a high-grade intraepithelial (VIN 3, carcinoma in situ) lesion associated with early invasive carcinoma in six cases and overt invasive carcinoma in one. By contrast, no evidence of early carcinoma was present in the ISCCs (group II). By in situ hybridization and/or Southern blot hybridization or polymerase chain reaction (PCR), HPV DNA was detected in all cases of group I and in four of 16 cases (25%) of group II, two only by Southern blot after PCR. By single-strand conformation polymorphism and immunocytochemistry only wild-type TP53 and absence of detectable p53 product, respectively, were found in all cases of group I, i.e., in high-risk HPV-positive carcinomas, whereas mutations and/or p53 overexpression accounted for 75% in group II, i.e., in mainly HPV-negative carcinomas. The TP53 gene mutations observed in invasive carcinomas were significantly related to node-positive cases (p = 0.04). Taken together and in agreement with in vitro data, these results support the view that an alteration of TP53, gained either by interaction with viral oncoproteins or by somatic mutations, is a crucial event in the pathogenesis of vulvar carcinomas, but that TP53 mutations are mainly associated with disease progression. Finally, a preliminary immunocytochemical analysis seems to speak against the possible involvement of both MDM2 and BCL-2 gene products in the development of vulvar carcinoma.

    2011-09-01

    Appendicoliths are formed by calcium salts and faecal debris layered and lodged within the appendix. They are detected on unenhanced x-rays in less than 10% of patients with appendicitis. When an appendicolith is found extraluminally, it is pathognomonic for perforation of the appendix. Moreover, retained appendicoliths act as a nidus for infection and are likely to be the source of a postoperative intraperitoneal abscess. However, this is very rare with only 30 reported cases of intra-abdominal abscess secondary to an appendicolith in the literature over the past 40 years. Retained, or dropped, appendicoliths most commonly present as an area of high attenuation less than 1cm in diameter with an associated abscess close to the caecum or Morrison's pouch on computed tomography (CT). A study published in 2006 showed that although there is initial success with CT-guided drainage of abscesses secondary to faecaliths, all will recur and formal surgical drainage with removal of the appendicolith is required. This case report highlights not only an unusual complication of a retained appendicolith but also the importance of taking a thorough history and interpreting investigations in the context of the patient's past medical history so as to produce a differential diagnosis and prevent treatment of incorrect conditions.

    Riedel's thyroiditis, known as invasive fibrous thyroiditis, is a very rare form of chronic thyroiditis. It is hard to make the diagnosis without surgical biopsy. We present a case of Riedel's thyroiditis in a 52-year-old female with past history of Hashimoto's thyroiditis. She suffered from bilateral neck pain, which radiated to both lower jaws. The erythrocyte sedimentation rate was 125 mm/hour. Subacute thyroiditis superimposed on Hashimoto's thyroiditis was diagnosed and treated with steroid. However the response was poor and she had a history of severe peptic ulcer. To avoid inducing the peptic ulcer by steroid, she received bilateral subtotal thyroidectomy. During surgery, the thyroid had severe adhesion to surrounding soft tissue and the pathology showed Riedel's thyroiditis. The neck pain improved after thyroidectomy. Tamoxifen has been given for 8 months and the size of remnant thyroid decreased to 8 mm. We concluded that combined thyroidectomy and tamoxifen successfully cured a patient with Riedel's thyroiditis.

    Reports of neuroectodermal primary scrotal tumors are scarce. Primary paratesticular neuroblastomas seem even rarer, and only five infants with this condition have been previously described. To the authors' knowledge, this would be the first report of a neonatal congenital paratesticular neuroblastoma. However, the authors postulate that ischemic compressive features in testis could lead to misdiagnosis as testicular torsion and the condition could usually go undetected. A newborn male baby with a left scrotal tumefaction was referred to the authors in May 2003. Doppler ultrasonography findings were inconclusive, and a diagnosis of intrauterine torsion of the testis was suspected. Surgery showed a paratesticular mass with a small attachment to an intra-abdominal epiploon. Pathologic examination clearly established the diagnosis of neuroblastoma. Cytogenetic findings (no amplification of N-myc oncogene, aneuploidy, and no deletion of chromosome 1p) were favorable. As the tumor was classified as International Neuroblastoma Staging System stage I, no additional chemotherapy was administered.

    Introduction Rectus sheath hematoma is an uncommon cause of acute abdominal pain. It is an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. It could occur spontaneously or after trauma. They are usually located infraumblically and often misdiagnosed as acute abdomen, inflammatory diseases or tumours of the abdomen. Case presentation We reported three cases of rectus sheath hematoma presenting with a mass in the abdomen and diagnosed by computerized tomography. The patients recovered uneventfully after bed rest, intravenous fluid replacement, blood transfusion and analgesic treatment. Conclusion Rectus sheath hematoma is a rarely seen pathology often misdiagnosed as acute abdomen that may lead to unnecessary laparotomies. Computerized tomography must be chosen for definitive diagnosis since ultrasonography is subject to error due to misinterpretation of the images. Main therapy is conservative management.

    Vulvar lichen sclerosis (VLS) is a chronic, inflammatory and mucocutaneous disease of extragenital skin, which often goes undetected for years. The underlying causes are associated with the decrease of VEGF that reduces the blood oxygenation of vulva and the structural changes in the collagen fibrils, which can lead to scarring of the affected area. However, few methods are available for quantitative detection of VLS. Clinician's examinations are subjective and may lead to misdiagnosis. Spectroscopy is a potentially effective method for noninvasive detection of VLS. In this paper, we developed a polarized, hyperspectral imaging system for quantitative assessment. The system utilized a hyperspectral camera to collect the reflectance images of the entire vulva under Xenon lamp illumination with and without a polarizer in front of the fiber. One image (Ipar) acquired with the AOTF parallel to the polarization of illumination and the other image (Iper) acquired with the AOTF perpendicular to the illumination. This paper compares polarized images of VLS in a pilot clinical study. The collected reflectance data under Xenon lamp illumination without a polarizer are calibrated and the hyperspectral signals are extracted. An IRB approved clinical trial was carried out to evaluate the clinical utility for VLS detection. Our pilot study has demonstrated the technical potential of using this polarized hyperspectral imaging system for in vivo detection of vulvar lichen sclerosis.

  16. Early invasive vulvar squamous cell carcinoma arising in a woman with vulvar pemphigus vulgaris and systemic lupus erythematosus

    2010-01-01

    Background Pemphigus vulgaris (PV) is an autoimmune blistering disease of the skin and mucous membranes. Genital involvement occurs when most other common sites are concurrently affected or are in remission. Systemic lupus erythematosus (SLE) is an autoimmune disease that may affect many parts of the body and the skin with occasional bullous lesions. Pemphigus vulgaris and SLE may be associated, albeit rarely. Here, we report the first case of a woman affected with SLE presenting with early invasive squamous cell carcinoma (SCC) arising from Pemphigus Vulgaris of the vulva. Case presentation A 27-year-old Caucasian woman was admitted to our Gynaecology Unit for bleeding vegetant lesions of the vulva. Her history was characterized by systemic lupus erythematosus and PV. Biopsy showed concomitant PV and vulvar intraepithelial neoplasia (VIN) grade 3. One month later a new biopsy revealed progression from VIN 3 to early SCC. Despite chemotherapy, no remission of disease was observed. She died six months after diagnosis Conclusion Our case underlines PV as another chronic inflammatory disease of the lower genital tract predisposing to VIN-SCC. It suggests the need for careful follow-up of patients with chronic inflammatory disease, especially when concomitant autoimmune disorders are present. Moreover, a biopsy should be always performed if there are PV lesions because of the possibility of neoplastic disease. PMID:20573220

    Several studies have shown that a woman's vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and 115 men, all of them college students and unacquainted with each other, participated in the study. Female odors were collected on pads affixed to the axilla and on panty protectors both worn the entire night before experiments. Men provided five saliva samples, a basal one before the smelling procedure, and four more 15, 30, 60, and 75 min after exposure to odors. Immediately after smelling the odor source, men answered a questionnaire rating hedonic qualities of scents, and after providing the last saliva sample they answered questionnaire on sexual desire. We found that periovulatory axillary and vulvar odors increased testosterone and cortisol levels, with vulvar scents producing a more prolonged effect. Luteal axilla odors decreased testosterone and cortisol levels, while luteal vulva odors increased cortisol. Periovulatory axilla and vulva scents accounted for a general increase of interest in sex. These odors were also rated as more pleasant and familiar, while luteal vulvar odors were perceived as intense and unpleasant.

    PubMed Central

    2013-01-01

    Status and emerging issues in the use of praziquantel for treatment of human trematode and cestode infections are briefly reviewed. Since praziquantel was first introduced as a broadspectrum anthelmintic in 1975, innumerable articles describing its successful use in the treatment of the majority of human-infecting trematodes and cestodes have been published. The target trematode and cestode diseases include schistosomiasis, clonorchiasis and opisthorchiasis, paragonimiasis, heterophyidiasis, echinostomiasis, fasciolopsiasis, neodiplostomiasis, gymnophalloidiasis, taeniases, diphyllobothriasis, hymenolepiasis, and cysticercosis. However, Fasciola hepatica and Fasciola gigantica infections are refractory to praziquantel, for which triclabendazole, an alternative drug, is necessary. In addition, larval cestode infections, particularly hydatid disease and sparganosis, are not successfully treated by praziquantel. The precise mechanism of action of praziquantel is still poorly understood. There are also emerging problems with praziquantel treatment, which include the appearance of drug resistance in the treatment of Schistosoma mansoni and possibly Schistosoma japonicum, along with allergic or hypersensitivity reactions against praziquantel treatment. To cope with and overcome these problems, combined use of drugs, i.e., praziquantel and other newly introduced compounds such as triclabendazole, artemisinins, and tribendimidine, is being tried.

    Sparganosis, caused by the plerocercoid larvae of members of the genus Spirometra, can cause significant public health problem and considerable economic losses. In the present study, the complete mitochondrial DNA (mtDNA) sequence of Spirometra erinaceieuropaei from China was determined, characterized and compared with that of S. erinaceieuropaei from Japan. The gene arrangement in the mt genome sequences of S. erinaceieuropaei from China and Japan is identical. The identity of the mt genomes was 99.1% between S. erinaceieuropaei from China and Japan, and the complete mtDNA sequence of S. erinaceieuropaei from China is slightly shorter (2 bp) than that from Japan. Phylogenetic analysis of S. erinaceieuropaei with other representative cestodes using two different computational algorithms [Bayesian inference (BI) and maximum likelihood (ML)] based on concatenated amino acid sequences of 12 protein-coding genes, revealed that S. erinaceieuropaei is closely related to Diphyllobothrium spp., supporting classification based on morphological features. The present study determined the complete mtDNA sequences of S. erinaceieuropaei from China that provides novel genetic markers for studying the population genetics and molecular epidemiology of S. erinaceieuropaei in humans and animals.

    PubMed Central

    2011-01-01

    Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.

    2011-10-01

    Melorheostosis is a rare osteosclerotic bone dysplasia. It is usually characterized by dull and aching pain, reduced joint motion and contractures. Classic radiograph findings are of undulating cortical hyperostosis along the length of the bone, simulating a "dripping candlewax appearance". We report two cases of melorheostosis of the ulna bone, diagnosed 6 years apart in two different females in their early 20s. Both the patients presented with the characteristic features of dull and aching pain in the forearm and were treated conservatively. However, we misdiagnosed the first case as bone malignancy and subjected the patient to a biopsy. For the second case, with hindsight we made the correct diagnosis based only on the classic clinical history and radiographs. We believe that the discussion of a misdiagnosed case of melorheostosis with salient findings may be important for clinicians and orthopedicians in day-to-day clinical practice. Copyright © 2011.

    Ganglioglioma is a rare, benign, intraaxial glioneuronal tumor but a relatively common cause of pharmacoresistant temporal lobe epilepsy (TLE). Given its often nonspecific neuropsychiatric manifestations and frequently negative electroencephalographic workup, TLE can be easily misdiagnosed as a psychiatric disorder, particularly panic attacks. We present a case of a 17-year-old boy who was found to have lesional TLE secondary to a left temporal ganglioglioma, 5 years after having been misdiagnosed with panic disorder and having undergone ineffective and unnecessary psychotherapy. He was successfully cured by surgery. Although a few similar cases of TLE masquerading as a panic disorder have been previously reported in the literature, this is the youngest and only pediatric patient described to date. This report underscores the challenges in making an accurate clinical diagnosis of TLE and the importance of timely brain imaging whenever an atypical or medically refractory panic disorder is encountered.

    In the past, total uterine prolapse in the sow has been regarded as a grave condition because manipulative reposition through the vulva and vagina is extremely difficult, if not impossible, and amputation is merely a salvage procedure with a mortality rate approaching 100 percent. Laparotomy as a means of facilitating reduction of the prolapse in the sow appears to have been overlooked although it is a standard procedure in dogs and cats. This report describes a case of uterine prolapse in a sow successfully treated by laparotomy.

It resembles Hystrignathus cobbi Travassos & Kloss, 1957 from Brazil, by having a similar form of the cephalic end, extension of cervical spines and absence of lateral alae. It differs from the latter species by having the body shorter, the oesophagus and tail comparatively larger, the vulva situated more posterior and the eggs ridged. This species constitutes the first record of a nematode parasitizing a Panamanian passalid. PMID:21594186

    In addition to cervical cancer, human papillomavirus (HPV) is responsible for a significant proportion of cancers and precancerous lesions of the vulva, vagina, anus, penis, head and neck, as well as genital warts. We estimated the annual number of new cases of these diseases attributable to 9-valent HPV vaccine types in women and men in Europe. The annual number of new cancers of the cervix, vulva, vagina, anus, penis, and selected head and neck sites in the population of the European Medicines Agency territory was estimated based on age-specific incidence rates extracted from Cancer Incidence in 5 Continents, Volume X and Eurostat population data for 2015. The annual number of new cancers attributable to 9-valent HPV vaccine types was estimated by applying the HPV attributable fraction from reference publications based on a large European multicenter study. For non-cervical cancers, HPV attributable fractions were based on oncogenically-active HPV infections only (i.e., detection of HPV DNA and either mRNA and/or p16 positivity). For precancerous lesions of the cervix, vulva, vagina, and anus, and for genital warts, previously published estimations were updated for the 2015 population. The annual number of new cancers attributable to 9-valent HPV vaccine types was estimated at 47,992 (95% bound: 39,785-58,511). Cervical cancer showed the highest burden (31,130 cases), followed by head and neck cancer (6,786 cases), anal cancer (6,137 cases), vulvar cancer (1,466 cases), vaginal cancer (1,360 cases), and penile cancer (1,113 cases). About 81% were estimated to occur in women and 19% in men. The annual number of new precancerous lesions (CIN2+, VIN2/3, VaIN2/3, and AIN2/3) and genital warts attributable to 9-valent HPV vaccine types was estimated at 232,103 to 442,347 and 680,344 to 844,391, respectively. The burden of cancers associated with 9-valent HPV vaccine types in Europe is substantial in both sexes. Head and neck cancers constitute a heavy burden

  4. Topical Benzocaine and Methemoglobinemia.

    PubMed

    Hieger, Michelle A; Afeld, Jamiee L; Cumpston, Kirk L; Wills, Brandon K

    Methemoglobinemia can cause life-threatening hypoxia associated with cyanosis and dyspnea not responsive to oxygen. We present a case of recurrent methemoglobinemia because of occult use of topical benzocaine to the vulva. A 47-year-old female with medical history of vulvar cancer and HIV undergoing chemoradiation was sent by the oncology clinic to the emergency department for worsening dyspnea, fatigue, hypoxia to 78% on room air, and gradual onset of cyanosis over the past week. A methemoglobin (MetHb) level was 49%. She received methylene blue, and repeat MetHb levels initially decreased but later increased to 56% despite continued treatment. Additional interviews with the patient revealed she was applying vagicaine (20% benzocaine), an over the counter preparation to the vulvar area for analgesia, and she continued application while hospitalized. She received a total of 6 mg/kg methylene blue and underwent vaginal lavage with 60 mL of sterile saline and cleansed with soapy water. Cyanosis, hypoxia, and dyspnea resolved, and the MetHb level decreased to 5.4% on the day of discharge. Benzocaine is a frequent cause of iatrogenic methemoglobinemia. In this case, additional medication inquiries were helpful in making the diagnosis. Many patients do not consider over-the-counter medications to be potentially harmful. Methemoglobinemia from occult topical benzocaine administration to the vulva is an uncommon exposure route. Occult medication use can be a source of methemoglobinemia.

    Objective The objective of this prospective pilot study was to assess the clinical and histologic effects of topical imiquimod therapy on recurrent extramammary Paget's disease of the vulva. Methods Patients with biopsy-proven recurrent extramammary Paget's disease presenting to the gynecology outpatient services at two participating institutions were recruited for conservative treatment with 5% imiquimod cream from 2007 to 2011. The topical cream was to be applied 3 times per week for 12 weeks. Punch biopsy and photography were performed at baseline and at the 12-week time point. Results Eight patients from two institutions were enrolled. Complete clinical and histologic response was achieved in 6 (75%) patients by the 12-week follow-up appointment. Of the two remaining patients, one had a complete clinical response but no significant histologic response; the other patient was removed from the study protocol secondary to intolerable local irritation. Two patients continue to have no evidence of disease after a median follow-up of 35 months. Five are alive with disease. No patients progressed to invasive cancer while receiving therapy. Conclusion Topical 5% imiquimod cream is a safe and feasible option for women suffering from recurrent extramammary Paget's disease of the vulva, and should be considered as a viable alternative to surgical management. Given the rare nature of this disease, additional multi-institutional prospective studies should be conducted to explore the efficacy of this treatment regime. PMID:27112632

    Cryphodera sinensis n. sp. is described from ramie (Boehmeria nivea) based on the morphology and molecular analyses of rRNA small subunit (SSU), D2D3 expansion domains of large subunit (LSU D2D3) and internal transcribed spacer (ITS). This new species is characterized by oval females with a distinct subcrystalline layer and pronounced and protruding vulval lip, distinctly concave vulva-anus profile and a vulva-anus distance of 29.5-35.8 μm. Males possess two annuli in the lip region, a stylet 27-32.5 μm in length with round knobs sloping slightly posteriorly, lateral fields with three lines, spicules 20-28 μm long and the presence of a short cloacal tube. Second-stage juveniles possess three lip annuli, a stylet 28-31 μm in length with well-developed knobs projected anteriorly and three lines along the lateral field. The pointed tail, 52-65 μm long, possesses a mucro-like tip and a hyaline region, 24.5-35 μm long. Large phasmids with a lens-like structure are located 2-6 annuli posterior to the anus. Phylogenetic analysis shows that the species has unique SSU, LSU D2D3 and ITS rRNA sequences. Phylogenetic relationships of the three rDNA sequences of C. sinensis n. sp. and other cystoid/cyst nematodes are analysed together with a comparison of other species within the genus Cryphodera.

    Heterodorus youbertghostai n. sp. is described and illustrated based on morphological, morphometric, and molecular data. The new species was found in two geographically distant points in northwestern Iran and is characterized by having angular lip region, separated from the rest body by a constriction, body length of 1,432.5 to 1,751.3 µm, odontostyle length of 24 to 28 µm, rod-like odontophore, 37.0 to 42.5 µm long, lacking flanges at base, double guiding ring at 14 to 16 µm distance from anterior end, pharyngeal bulb comprising 40% to 48% of pharynx, intestine usually containing green material, female reproductive system amphidelphic with less divided short uterus, specific structure of pars distalis vaginae, bluntly conical tail, dorsally convex and ventrally flat, with rounded tip and saccate bodies in ventral side. The new species comes more close to H. conicaudatus and H. irregularis by its morphology and morphometric characters. Compared to former, it has remarkable difference in vulva position and tail characters, and compared to the latter, it could be separated by shorter body, posteriorly located vulva, wider lip region, and longer tail. In phylogenetic analyses using partial sequences of 28S rDNA D2-D3, the new species formed a fully supported clade with several isolates of H. brevidentatus, prevalent in Iran. The other nordiid taxon, Enchodorus dolichurus, already reported from Iran, was also sequenced for the same genomic region and included in phylogenetic analyses.

    The aim of the present study was to elucidate the clinico-pathological characteristics of female patients with lower genital tract rhabdomyosarcoma (RMS) stratified by age group and investigate their prognosis, using a multi-institutional database. The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database was accessed (1973-2013) and a cohort of females diagnosed with RMS of the lower genital tract (vulva, vagina, cervix) was drawn. Five-year overall survival (OS) rate was estimated following generation of Kaplan-Meier curves and compared with the log-rank test. A total of 144 eligible cases were identified; 51.4 and 48.6% originated from the vagina/vulva and the cervix, respectively. Median patient age was 16 years and distant metastases were rare (ten cases). The majority of tumors were of embryonal histology (75.7%). Non-embryonal RMS was more prevalent in the older patient groups. Tumors originating from the cervix were more common among adolescents and premenopausal women. Rate of LN involvement was 52.9 and 20% for vulvovaginal and cervical tumors (p = 0.02). Five-year OS rate was 68.4%; factors associated with better OS were younger age, absence of distant metastasis, embryonal histology, negative LNs, and performance of surgery. For prepubertal girls and adolescents, radical surgery did not confer a survival benefit compared to local tumor excision. RMS of the lower genital tract primarily affects prepubertal girls and adolescents, who have excellent survival rates; however, outcomes for adults remain poor.

    In the present study, we examined certain features of the functional anatomy of the female genital tract of the wild brush-tailed porcupine (Atherurus africanus) to obtain data on the reproductive biology of this African forest rodent. Two consecutive experiments were performed. The aim of the first was to establish macroscopic and microscopic features of the genital organs, and to explore correlations between predominant ovarian structures and vaginal contents in 20 wild, mature females. In the second experiment, we inspected the external genitalia and vaginal smears of a further 10 females in captivity on a daily basis for 90 days. The uterus of the brush-tailed porcupine is bicornuate and composed of two separated uterine horns, a uterine body and cervix. The genital tract does not present a vaginal vestibule. Thus, there is no portion common to genital and urinary tracts. Females in the follicular phase of the oestrous cycle showed increased cornification of the vaginal epithelium and a high density of eosinophilic cells in vaginal smears. The vulva and vaginal opening were open, reddish and tumefacted. In luteal phase or in pregnancy, epithelial cornification and eosinophilic features were notably reduced and the vagina presented a pale, non-tumefacted vulva and a vaginal closure membrane. Females in captivity showed spontaneous cycles, a polyoestrous reproduction pattern and, based on features of the external genitalia and vaginal smears, their oestrous cycle length was 27.1+/-6.4 days (n=12).

    Penetration of a male copulatory organ into a suitable mate is a conserved and necessary behavioral step for most terrestrial matings; however, the detailed molecular and cellular mechanisms for this distinct social interaction have not been elucidated in any animal. During mating, the Caenorhabditis elegans male cloaca is maintained over the hermaphrodite's vulva as he attempts to insert his copulatory spicules. Rhythmic spicule thrusts cease when insertion is sensed. Circuit components consisting of sensory/motor neurons and sex muscles for these steps have been previously identified, but it was unclear how their outputs are integrated to generate a coordinated behavior pattern. Here, we show that cholinergic signaling between the cloacal sensory/motor neurons and the posterior sex muscles sustains genital contact between the sexes. Simultaneously, via gap junctions, signaling from these muscles is transmitted to the spicule muscles, thus coupling repeated spicule thrusts with vulval contact. To transit from rhythmic to sustained muscle contraction during penetration, the SPC sensory-motor neurons integrate the signal of spicule's position in the vulva with inputs from the hook and cloacal sensilla. The UNC-103 K+ channel maintains a high excitability threshold in the circuit, so that sustained spicule muscle contraction is not stimulated by fewer inputs. We demonstrate that coordination of sensory inputs and motor outputs used to initiate, maintain, self-monitor, and complete an innate behavior is accomplished via the coupling of a few circuit components.

    During a helminthological examination of marine fishes from south of the Minnan-Taiwan Bank Fishing Ground, Taiwan Strait, Fujian, China, a new cucullanid nematode, Dichelyne (Cucullanellus) jialaris n. sp., was removed from the intestine of the red seabream, Pagrus major (Temminck & Schlegel, 1834). The new species differs from its congeners mainly in the following characters: body size medium but with relative long spicules of 1.01 mm (0.97-1.06) in length or 20.0% (18.21-21.8%) of the body length; proximal end of spicules somewhat expanded and distal end rounded; gubernaculum I-shaped, slightly narrow in the middle part, both ends rounded; both anterior and posterior cloaca lips round or oval, prominent and unequal in size. The anterior cloaca lip is at least 2 times larger than the posterior one. There is a conspicuous papilliform structure within the central of anterior and posterior cloacal lip. Vulva of female is not prominent, slightly postequatorial; distance from vulva to anterior end of body is 4.3 (3.0-5.5) mm or 58.0% (54.0-62.0%) of the body length. Considering the result of comparing the structure of so-called unpaired median papilla with the 10 pairs of caudal petiolated papillae in the body of the same individual. the papilliform structures are just a backstop for the cloacal lips, this new species represents the first record of a nematode of the Dichelyne, subgenus Cucullanellus in marine fishes of China Sea.

    Although the physical adverse effects following surgery for vulval cancer may readily be described, little is known about the psychological, emotional, and social impact. A review of the literature revealed a paucity of studies, as this condition is rare. To explore the lived experiences of women in the United Kingdom with vulval cancer, a qualitative research study was undertaken using the research methodology of interpretive phenomenology, based on the work of Heidegger (The Essence of Human Freedom. London: Continuum; 2005) and van Manen (Researching Lived Experience. Human Science for an Action Sensitive Pedagogy. New York: State University of New York Press; 1990). Thirteen women younger than 50 years were interviewed between 6 months and 5 years after their surgery, and the data were analyzed using framework analysis (Qualitative data analysis for applied policy research. In: Analysing Qualitative Data. London: Routledge; 1994:173-194). This article describes how the concept of searching emerged from the data. It also describes the manner in which the women searched to control their symptoms by their own efforts and by undergoing surgery. The search to understand the truth about their condition and their access to information in the search for meaning and the time element in which this was undertaken was also raised. An underlying consideration is the need for health professionals to help provide the information and support needed to manage this condition.

    A 61-year-old woman, who was known to have Hailey-Hailey disease, presented with increasing vulval soreness. Biopsy showed vulval intraepithelial neoplasia (VIN) 3 and subsequent histology from a vulvectomy specimen showed extensive VIN with early invasive squamous cell carcinoma. This may be another example of chronic inflammation of the vulval area leading to the development of squamous cell carcinoma. However, in this case, chronic human papillomavirus may also have played a part, leading to VIN and reactivation of the Hailey-Hailey disease. We can find no previous reports of squamous cell carcinoma developing in the setting of Hailey-Hailey disease.

    Summary Growing evidence has established two major types of vulvar intraepithelial neoplasia (VIN), which correspond to two distinct oncogenic pathways to vulvar squamous cell carcinoma (VSCC). While the incidence of VSCC has remained relatively stable over the last three decades, the incidence of VIN has increased. VIN of usual type (uVIN) is human papillomavirus (HPV)-driven, affects younger women and is a multicentric disease. In contrast, VIN of differentiated type (dVIN) occurs in post-menopausal women and develops independent of HPV infection. dVIN often arises in a background of lichen sclerosus and chronic inflammatory dermatoses. Although isolated dVIN is significantly less common than uVIN, dVIN bears a greater risk for malignant transformation to VSCC and progresses over a shorter time interval. On histological examination, uVIN displays conspicuous architectural and cytological abnormalities, while the morphological features that characterise dVIN are much more subtle and raise a wide differential diagnosis. On the molecular level, dVIN is characterised by a higher number of somatic mutations, particularly in TP53. Here we review the classification, epidemiology, clinical features, histomorphology, ancillary markers and molecular genetics of both types of VIN, and discuss the morphological challenges faced by pathologists in interpreting these lesions.

    Vuval pathologies manifested by allodynia and burning sensations can be due to infection, inflammatory dermatoses or other causes. Infective as well as certain inflammatory diseases, e.g. drug eruptions, allergic eczemas, irritative dermatitis/vulvitis, Behcet's Syndrome and pemphigus/pemphigoid usually respond well to conservative treatment. The category of inflammatory diseases also contains pathologies that in certain circumstances do require a surgical intervention, e.g. Lichen ruber planus/Lichen sclerosus, Condyloma, scars, premalignant lesions (VIN, genital M. Paget) and cancer. Vulodynia also can cause some stinging to the vulvar skin. The surgical aspects relating to the treatment of the benign and premalignant pathologies indicated above are mentioned in this mini-review.

    2011-01-01

    Appendicoliths are formed by calcium salts and faecal debris layered and lodged within the appendix. They are detected on unenhanced x-rays in less than 10% of patients with appendicitis. When an appendicolith is found extraluminally, it is pathognomonic for perforation of the appendix. Moreover, retained appendicoliths act as a nidus for infection and are likely to be the source of a postoperative intraperitoneal abscess. However, this is very rare with only 30 reported cases of intra-abdominal abscess secondary to an appendicolith in the literature over the past 40 years. Retained, or dropped, appendicoliths most commonly present as an area of high attenuation less than 1cm in diameter with an associated abscess close to the caecum or Morrison’s pouch on computed tomography (CT). A study published in 2006 showed that although there is initial success with CT-guided drainage of abscesses secondary to faecaliths, all will recur and formal surgical drainage with removal of the appendicolith is required. This case report highlights not only an unusual complication of a retained appendicolith but also the importance of taking a thorough history and interpreting investigations in the context of the patient’s past medical history so as to produce a differential diagnosis and prevent treatment of incorrect conditions.

    The 2015 neonatal resuscitation guidelines added ECG as a recommended method of assessment of an infant's heart rate (HR) when determining the need for resuscitation at birth. However, a recent case report raised concerns about this technique in the delivery room. To compare accuracy of ECG with auscultation to assess asystole in asphyxiated piglets. Neonatal piglets had the right common carotid artery exposed and enclosed with a real-time ultrasonic flow probe and HR was continuously measured and recorded using ECG. This set-up allowed simultaneous monitoring of HR via ECG and carotid blood flow (CBF). The piglets were exposed to 30 min normocapnic alveolar hypoxia followed by asphyxia until asystole, achieved by disconnecting the ventilator and clamping the endotracheal tube. Asystole was defined as zero carotid blood flow and was compared with ECG traces and auscultation for heart sounds using a neonatal/infant stethoscope. Overall, 54 piglets were studied with a median (IQR) duration of asphyxia of 325 (200-491) s. In 14 (26%) piglets, CBF, ECG and auscultation identified asystole. In 23 (43%) piglets, we observed no CBF and no audible heart sounds, while ECG displayed an HR ranging from 15 to 80/min. Sixteen (30%) piglets remained bradycardic (defined as HR of <100/min) after 10 min of asphyxia, identified by CBF, ECG and auscultation. Clinicians should be aware of the potential inaccuracy of ECG assessment during asphyxia in newborn infants and should rather rely on assessment using a combination of auscultation, palpation, pulse oximetry and ECG. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To analyze the most common neurophthalmological conditions that may mimic glaucomatous optic neuropathy and to determine which most often lead to misdiagnosis when evaluated by a glaucoma specialist. We reviewed the charts of consecutive patients with optic neuropathies caused by neurophthalmological conditions screened in a single Eye Clinic within a period of 24 months. Within these enrolled patients, we selected the eyes whose fundoscopic appearance could resemble glaucoma based in pre-defined criteria (vertical cup-to-disc ratio ≥0.6, asymmetry of the cup-to-disc ratio ≥0.2 between eyes, presence of localized retinal nerve fiber layer and/or neuroretinal rim defects, and disc haemorrhages). Then, color fundus photographs and Humphrey Visual Field tests (HVF) of these eyes were mixed with tests from 21 consecutive glaucomatous patients (42 eyes with normal tension glaucoma). These images were mixed randomly and a masked glaucoma specialist was asked to distinguish if each set of exams was from a patient with glaucoma or with a neurophthalmologic condition. Among the 101 eyes (68 patients) enrolled with neurophthalmological diseases, 16 (15.8%) were classified as conditions that could mimic glaucoma. The most common diagnoses were ischemic optic neuropathy (25%), compressive optic neuropathy (18.7%) and hereditary optic neuropathy (18.7%). Based on the analysis of fundus photographs and HVF tests, 25% of these were misdiagnosed as glaucoma (two ischemic optic neuropathies and two congenital optic disc anomalies). Conversely, 11.9% of the glaucomatous neuropathies were misdiagnosed as neurophthalmological disorders. Overall, the glaucoma specialist correctly diagnosed 84.5% of the eyes. Some neurophthalmological disorders can mimic glaucoma. In our study, isquemic and compressive optic neuropathies were the ones that most often did so. Almost one quarter of the eyes were misdiagnosed when evaluated by a glaucoma specialist, which can lead to inadequate

    Objectives To identify the misdiagnoses of patients with sporadic Jakob-Creutzfeldt disease (sCJD) during the course of their disease and determine which medical specialties saw patients with sCJD prior to the correct diagnosis being made and at what point in the disease course a correct diagnosis was made. Design Retrospective medical record review. Setting A specialty referral center of a tertiary academic medical center. Participants One hundred sixty-three serial patients over a 5.5-year period who ultimately had pathologically proven sCJD. The study used the subset of 97 patients for whom we had adequate medical records. Main Outcome Measures Other diagnoses considered in the differential diagnosis and types of medical specialties assessing patients with sCJD. Results Ninety-seven subjects’ records were used in the final analysis. The most common disease categories of misdiagnosis were neurodegenerative, autoimmune/paraneoplastic, infectious, and toxic/metabolic disorders. The most common individual misdiagnoses were viral encephalitis, paraneoplastic disorder, depression, vertigo, Alzheimer disease, stroke, unspecified dementia, central nervous system vasculitis, peripheral neuropathy, and Hashimoto encephalopathy. The physicians who most commonly made these misdiagnoses were primary care physicians and neurologists; in the 18% of patients who were diagnosed correctly at their first assessment, the diagnosis was almost always by a neurologist. The mean time from onset to diagnosis was 7.9 months, an average of two-thirds of the way through their disease course. Conclusions Diagnosis of sCJD is quite delayed. When evaluating patients with rapidly progressive dementia with suspected neurodegenerative, autoimmune, infectious, or toxic/metabolic etiology, sCJD should also be included in the differential diagnosis, and appropriate diagnostic tests, such as diffusion brain magnetic resonance imaging, should be considered.

    Fungal infections of the skin are a common condition, usually easy to diagnose and treat. When the infection is clinically mimicking another cutaneous disorder or when the clinical presentation is modified by the use of inappropriate treatment, it is referred to as tinea atypica or tinea incognito.We report a series of nine cases of patients with tinea atypica, imitating and diagnosed initially as different skin diseases. Two patients were defined as pyoderma in the facial and pubic regions (caused respectively by Trichophyton mentagrophytes var. mentagrophytes and Microsporum canis) and one as herpes zoster ophthalmicus (caused by Trichophyton rubrum). Six additional patients were initially misdiagnosed: (1) Plaque-like formation of the skin misdiagnosed as an impetiginized eczema (with isolated agent Trichophyton verrucosum). (2) A rare form of skin infection of the hand caused by T. rubrum, imitating clinically cutaneous infection with tuberculum mulgentium. (3) Rosacea-like dermatitis with an isolated agent Fusarium. (4) A patient with the typical clinical symptoms of seborrheic dermatitis of the face (and with isolated T. rubrum as a causative agent). (5) Another patient presented with a widespread folliculitis by Trichophyton mentagrophytes. (6) In a patient with bullous pemphigoid and immunosuppression pemphigoid-like eruptions were caused by Malassezia pachydermatis and T. rubrum. The diagnosis in the presented cases was based on direct microscopic examination with KOH and a culture on Sabouraud agar.After the diagnosis of tinea, treatment with topical and systemic antifungal agents was administrated, followed by complete clinical remissions in all cases.The clinical manifestations of tinea atypica can mimic a large number of other dermatoses, which often leads to misdiagnosing, and as a consequence--to serious difficulties in the management of clinical symptoms and in offering appropriate therapy.

    The failure to recognize an ischemic stroke in the emergency department is a missed opportunity for acute interventions and for prompt treatment with secondary prevention therapy. Our study examined the diagnosis of acute ischemic stroke in the emergency department of an academic teaching hospital and a large community hospital. A retrospective chart review was performed from February 2013 to February 2014. A total of 465 patients with ischemic stroke were included in the analysis; 280 patients from the academic hospital and 185 patients from the community hospital. One hundred three strokes were initially misdiagnosed that is 22% of the included strokes at the combined centers. Fifty-five of these were missed at the academic hospital (22%) [corrected] and 48 were at the community hospital (26%, P=0.11). Thirty-three percent of missed cases presented within a 3-hour time window for recombinant tissue-type plasminogen activator eligibility. An additional 11% presented between 3 and 6 hours of symptom onset for endovascular consideration. Symptoms independently associated with greater odds of a missed stroke diagnosis were nausea/vomiting (odds ratio, 4.02; 95% confidence interval, 1.60-10.1), dizziness (odds ratio, 1.99; 95% confidence interval, 1.03-3.84), and a positive stroke history (odds ratio, 2.40; 95% confidence interval, 1.30-4.42). Thirty-seven percent of posterior strokes were initially misdiagnosed compared with 16% of anterior strokes (P<0.001). Atypical symptoms associated with posterior circulation strokes lead to misdiagnoses. This was true at both an academic center and a large community hospital. Future studies need to focus on the evaluation of identification systems and tools in the emergency department to improve the accuracy of stroke diagnosis. © 2016 American Heart Association, Inc.

    Type A aortic dissection with concurrent ST-elevation myocardial infarction (STEMI) is relatively rare. However, it can be potentially fatal and easily misdiagnosed as STEMI alone. Misdiagnosis will lead to inappropriate administration of anticoagulant and thrombolytic therapy and delayed surgical repair of the aorta. In patients with STEMI, short reperfusion time is associated with improved survival, and minimizing the door-to-balloon time is the goal of therapy worldwide. However, signs critical for differential diagnosis may be overlooked in the rush to primary percutaneous coronary intervention. When a patient is encountered who presents with chest pain and ST elevation on electrocardiogram, STEMI should not be the only diagnosis considered. By using bedside available information, detailed history taking and focused physical examination, it is possible to avoid a mistaken diagnosis. Here we report a case of Stanford type A aortic dissection with STEMI that was initially misdiagnosed as sole acute inferior wall myocardial infarction. Patient mortality may have resulted from delayed diagnosis and surgical treatment. Acute myocardial infarction; Aortic dissection.

    Toxocariasis is a worldwide zoonosis caused by larvae of ascarid nematodes of dogs or cats, Toxocara canis or T. cati. Diagnosis of human toxocariasis currently relies on serology that uses T. canis excretory-secretory antigen to detect specific IgG antibodies by ELISA. We investigated the serodiagnostic efficacy of ELISA using crude antigen of T. canis larvae (TCLA). Serum specimens of 64 clinically confirmed toxocariasis, 115 healthy controls, and 119 other tissue-invading helminthiases were screened by ELISA using TCLA. The ELISA using TCLA showed 92.2% (59/64 patient samples) sensitivity and 86.6% (103/119) specificity. Its positive diagnostic predictivity was 78.7% and negative predictivity was 97.8%. No serum of healthy controls reacted but that of anisakiasis (45.5%), gnathostomiasis (19.2%), clonorchiasis (15.8%), sparganosis (11.1%), and cysticercosis (6.3%) cross-reacted. Immunoblot analysis on TCLA recognized antigenic proteins of 28- and 30-kDa bands in their dominant protein quantity and strong blotting reactivity. The present results indicate that the ELISA using our TCLA antigen is acceptable by the sensitivity and specificity for serodiagnosis of human toxocariasis. ELISA with TCLA is recommended to make differential diagnosis for patients with any sign of organ infiltration and eosinophilia. PMID:24039286

    Although helminth infections of the central nervous system (CNS) are rare, their public health implications must not be neglected. Indeed, several helminth species can cause cerebrospinal infections, especially if humans serve as intermediate or non-permissive host. The diagnosis of cerebrospinal helminthiases is difficult, and the detection of parasites in cerebrospinal fluid is rarely successful. Cerebrospinal helminth infections therefore often remain undetected, and hence prognosis is poor. Increases in tourism and population movements are risk factors for cerebrospinal helminthiases and infections pose particular challenges to clinicians in non-endemic areas. In this review, we focus primarily on food-borne helminthiases that are endemic and often emerging in Southeast Asia and the Far East, namely angiostrongyliasis, gnathostomiasis, sparganosis, paragonimiasis and cysticercosis. Additionally, we discuss neuroschistosomiasis, a disease that is transmitted through human-water contact. For each disease, we describe the pathogen, its transmission route and possible mechanisms for entering the CNS. We also summarise common signs and symptoms, challenges and opportunities for diagnosis, treatment, clinical management, geographical distribution and epidemiology. The adoption of a comprehensive set of diagnostic criteria for different cerebrospinal helminthiases is proposed, including epidemiological history, typical signs and symptoms, neuroimaging and laboratory findings. Finally, risk factors, and research needs for enhanced patient management and population-based control measures are discussed.

    The aim of this study was to assess the variability of temperatures measured by a video-based infrared camera (IRC) in comparison to rectal and vaginal temperatures. The body surface temperatures of cows and calves were measured contactless at different body regions using videos from the IRC. Altogether, 22 cows and 9 calves were examined. The differences of the measured IRC temperatures among the body regions, i.e. eye (mean: 37.0 °C), back of the ear (35.6 °C), shoulder (34.9 °C) and vulva (37.2 °C), were significant (P < 0.01), except between eye and vulva (P = 0.99). The quartile ranges of the measured IRC temperatures at the 4 above mentioned regions were between 1.2 and 1.8 K. Of the investigated body regions the eye and the back of the ear proved to be suitable as practical regions for temperature monitoring. The temperatures of these 2 regions could be gained by the use of the maximum temperatures of the head and body area. Therefore, only the maximum temperatures of both areas were used for further analysis. The data analysis showed an increase for the maximum temperature measured by IRC at head and body area with an increase of rectal temperature in cows and calves. The use of infrared thermography videos has the advantage to analyze more than 1 picture per animal in a short period of time, and shows potential as a monitoring system for body temperatures in cattle.

    The objectives of this study were to evaluate the occurrence of Leishmania infantum in the male and female genital tract and female mammary glands of dogs and the parasite burden and to identify histological alterations associated with this protozoan. Twenty male and 20 female Leishmania-seropositive dogs with isolation of L. infantum were examined. Tissue samples of the prepuce, glans, epididymis, testes, prostate, vulva, vagina, uterus, uterine tubes, and mammary glands were analyzed by immunohistochemistry and histopathology. For parasitological culture and in situ hybridization, samples were collected from the testis, epididymis, and uterus. Additionally, seminal fluid was aspirated from the epididymis for parasitological culture. In the genital tract, 34 (85 %) dogs, including 18 males and 16 females, were positive for Leishmania. Of these, 27 (79 %) animals were symptomatic. Leishmania was detected in the mammary glands of 13 (65 %) females. L. infantum was isolated for the first time from the seminal fluid and uterus of naturally infected dogs. The parasite burden and intensity of the inflammatory reaction were greater in the prepuce and glans of males and in the vulva and mammary glands of females. In addition to inflammation, testicular degeneration, atrophy, absence of spermatogenesis, and necrosis were observed. Detection of amastigote forms in the mammary gland lumen indicates possible elimination of this parasite in milk. The frequent parasitism observed in the genital tract of infected males and females and the viability of L. infantum in seminal fluid and uterus suggest the possibility of bidirectional venereal and vertical transmission.

    Human papillomavirus (HPV) infection is associated with high-grade vulvar intraepithelial neoplasia (VIN-3). The prevalence of anogenital HPV infection in women with previously treated VIN-3 has not been documented yet. This cross-sectional study compared high-risk HPV DNA detection rates in women with past (n = 30) and current (n = 22) VIN-3 to those without current or past VIN (n = 86). HPV DNA was detected in vulvar and cervical samples with Hybrid Capture 2 (HC-2). Smoking was associated in multivariate analysis with current VIN-3 (odds ratio (OR) 8.3, 95% confidence interval (CI) 2.0-8.2) and any VIN-3 history (OR 6.5, 95% CI 2.5-16.5). High-risk HPV DNA was found on the vulva of 64%, 33%, and 20% of women with current VIN-3, past VIN-3, and without previous or current VIN, respectively. After controlling for age and smoking, high-risk HPV vulvar infection was associated with cervical high-risk HPV infection (OR 8.6, 95% CI 2.8-26.5; P = 0.001). After controlling for age, HPV infection was more often multifocal in women with current VIN-3 compared to women with previous but no current VIN-3 lesion (OR 17.6, 95% CI 1.4-227.2). Multifocal vulvar HPV infection was detected in women with previous or active VIN-3. Longitudinal studies are required to determine if the multifocality of HPV infection on the vulva could explain the high recurrence rate of VIN-3.

    During recent decades it has become apparent that there are two types of vulvar disease: the classic type found in elderly women with unicentric and unifocal lesions, and the type found in younger women, in which precancerous and invasive changes develop in the anogenital lower tract in a multicentric and multifocal fashion, often over a long period of observation. The laminin-5 gamma 2 chain is an extracellular protein that is a component of the basement membrane. Recently its expression has been recognized as a marker in cervical cancer that permits identification of invasive capacity. The aim of our study was to determine if laminin-5 gamma 2 chain antibody can act as a sensitivity marker of invasive capacity in precancerous and invasive carcinoma in women with uni- and multifocal changes in the anogenital tract. The result showed that all patients in the older group of women with invasive carcinoma of the vulva had moderate to high positive expression of the laminin-5 gamma 2 chain. In the group of younger patients with multifocal precancerous changes observed over long periods, most of the patients with vulva intraepithelial neoplasia (VIN) 3 showed laminin-5 gamma 2 chain positivity already in the precancerous changes, and all of them developed invasivity during the period of observation. Normal epithelium without atypia was mostly negative or of low immunoreactivity of laminin-5. In conclusion, positive laminin-5 gamma 2 chain expression seems to indicate the invasiveness potential of precancerous lesions and is also expressed in all investigated invasive carcinomas of the anogenital tract.

    A 11-year-old, female, spayed greyhound was presented with a haemorrhagic discharge from the vulva. Clinical examination, vaginoscopy and a computed tomography scan showed an irregular egg-sized mass in the region of the cervix and uterine stump. An endoscopic grab biopsy (incisional) suggested a malignant mesenchymal tumour. Following this, surgical excision of the cranial vagina, cervix and the uterine remnant was performed. The final diagnosis of haemangiosarcoma was based on histological examination of the larger excisional biopsy specimen and was confirmed by positive immunolabelling of the neoplastic endothelial cells for the von Willebrand factor.

    Extramammary Paget's disease is a rare neoplasm of apocrine gland-bearing areas of the skin. The most common site of presentation is the vulva. Surgery is the most frequently reported therapy so far; however, it is invasive and it is complicated by a high rate of recurrence. For this reason, several less-invasive treatments have been recently proposed, including photodynamic therapy. We describe in this article the case of an 84-year-old patient with a noninvasive vulvar extramammary Paget's disease successfully treated with methyl-aminolevulinic acid photodynamic therapy associated with topical tretinoin. © 2013 Wiley Periodicals, Inc.

    Chylous ascites is an unusual condition with many causes. Two cases are presented in which it appeared to be related to whole pelvis irradiation in one patient for carcinoma of the vagina and in another for carcinoma of the vulva. The diagnosis is made by paracentesis and analysis of the fluid. The underlying disease usually requires identification by exploratory laparotomy. Although a malignant process is the most common cause, the only findings in the authors' cases were widespread radiation changes in the intestine. After diagnosis treatment by low-fat diet with medium-chain triglyceride supplements resulted in disappearance of chylous ascites.

    This article discusses the clinical evaluation and approach to patients with 3 complex ulcerative vulvar conditions: hidradenitis suppurativa, metastatic Crohn disease of the vulva, and aphthous ulcers. These conditions are particularly challenging to medical providers because, although each is known to present with nonspecific examination findings that vary in morphology, the predominance of the diagnosis is based on clinical examination and exclusion of a wide variety of other conditions. Care of patients with these conditions is further complicated by the lack of therapeutic data and the significant impact these conditions have on quality of life. Copyright © 2017 Elsevier Inc.

    Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. Most cases are asymptomatic; however, when symptomatic, it is often misdiagnosed at presentation. Common complications presenting in adults include bleeding, obstruction, diverticulitis, and perforation. Tumors within a Meckel's diverticulum are rare. Herein, we present a gastrointestinal stromal tumor arising from the Meckel's diverticulum that led to intestinal obstruction by volvulus.

    A significant proportion of mucosal melanomas contain alterations in KIT. The aim of this study was to characterize the pattern of KIT, NRAS, and BRAF mutations in mucosal melanomas at specific sites and to assess activation of the KIT downstream RAF/MEK/extracellular signal-regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K)/AKT pathways in mucosal melanoma specimens. Seventy-one primary mucosal melanomas from various sites were studied. Mutation analysis was done by DNA sequencing. Expression of KIT, phosphorylated (p)-ERK, and p-AKT was evaluated by immunohistochemistry. KIT mutations were detected in 35% (8 of 23) of vulvar, 9% (2 of 22) of anorectal, 7% (1 of 14) of nasal cavity, and 20% (1 of 5) of penile melanomas. No KIT mutations were found in 7 vaginal melanomas. The difference in KIT mutation frequency between vulvar and nonvulvar cases was statistically significant (P = 0.014). The overall frequencies of NRAS and BRAF mutations were 10% and 6%, respectively. Notably, vaginal melanomas showed a NRAS mutation rate of 43%. KIT gene amplification (≥4 copies), as assessed by quantitative real-time PCR, was observed in 19% of cases. KIT expression was associated with KIT mutation status (P < 0.001) and was more common in vulvar than nonvulvar tumors (P = 0.016). Expression of p-ERK and p-AKT was observed in 42% and 59% of tumors, respectively, and occurred irrespective of KIT/NRAS/BRAF mutation status. NRAS mutation was associated with worse overall survival in univariate analysis. Results show that KIT mutations are more common in vulvar melanomas than other types of mucosal melanomas and that both the RAF/MEK/ERK and PI3K/AKT pathways are activated in mucosal melanoma specimens. ©2011 AACR.

    Rapid diagnostic tests (RDTs) are the primary diagnostic tools for HIV used in resource-constrained settings. Without a proper confirmation algorithm, there is concern that false-positive (FP) RDTs could result in misdiagnosis of HIV infection and inappropriate antiretroviral treatment (ART) initiation, but programmatic data on FP are few. We examined the accuracy of RDT diagnosis among HIV-infected pregnant women attending public sector antenatal services in Cape Town, South Africa. We describe the proportion of women found to have started on ART erroneously due to FP RDT results based on pre-ART viral load (VL) testing and enzyme-linked immunosorbent assay (ELISA). We analysed 952 consecutively enrolled pregnant women diagnosed as HIV infected based on two RDTs per local guideline and found 4.5% (43/952) of pre-ART VL results to be <50 copies/ml. After excluding 6 women who had detectable virus on subsequent VL measurements, ELISA was performed on the 37 remaining women. Of these, 3/952 (0.3%) HIV RDT diagnoses were found to be FP. We estimate that using ELISA to confirm all positive RDTs would cost $1110 (uncertainty interval $381-$5382) to identify one patient erroneously initiated on ART, while it costs $3912 for a lifetime of antiretrovirals with VL monitoring for one person. Compared to the cost of confirming the RDT-based diagnoses, the cost of HIV misdiagnosis is high. While testing programmes based on RDT should strive for constant quality improvement, where resources permit, laboratory confirmation algorithms can play an important role in strengthening the quality of HIV diagnosis in the era of universal ART.

    Myasthenia gravis (MG) is an autoimmune disorder presenting with fluctuating, fatigable muscle weakness. Initial symptoms classically involve ocular and proximal limb muscles. Rarely, MG may onset with unusual features, so it can be misdiagnosed with other neuromuscular diseases. To describe unusual and atypical presentations of MG in a large cohort of patients, considering and discussing diagnostic difficulties and pitfalls. We report on 21 out of 508 MG patients, coming to our department in the last 27 years and presenting with atypical or unusual features. The diagnosis was achieved performing a careful clinical examination, a proper neurophysiological assessment, the neostigmine test, the AChR and MuSK antibodies assay and chest CT-scan. Patients with atypical/unusual MG onset were the 4.4% of all MG patients population. We describe seven different clinical categories: asymmetric distal upper limbs weakness, foot drop, isolated triceps brachii weakness and foot drop, post exertional axial weakness with dropped head, acute facial dyplegia, limb-girdle MG and MG with sudden lower limbs weakness and recurrent falls. Atypical and unusual presentations may increase the risk to misdiagnose or delay MG diagnosis. Isolated limb-girdle presentation is the most frequent atypical form in our series.

  8. Tracking a Medically Important Spider: Climate Change, Ecological Niche Modeling, and the Brown Recluse (Loxosceles reclusa)

    Most spiders use venom to paralyze their prey and are commonly feared for their potential to cause injury to humans. In North America, one species in particular, Loxosceles reclusa (brown recluse spider, Sicariidae), causes the majority of necrotic wounds induced by the Araneae. However, its distributional limitations are poorly understood and, as a result, medical professionals routinely misdiagnose brown recluse bites outside endemic areas, confusing putative spider bites for other serious conditions. To address the issue of brown recluse distribution, we employ ecological niche modeling to investigate the present and future distributional potential of this species. We delineate range boundaries and demonstrate that under future climate change scenarios, the spider's distribution may expand northward, invading previously unaffected regions of the USA. At present, the spider's range is centered in the USA, from Kansas east to Kentucky and from southern Iowa south to Louisiana. Newly influenced areas may include parts of Nebraska, Minnesota, Wisconsin, Michigan, South Dakota, Ohio, and Pennsylvania. These results illustrate a potential negative consequence of climate change on humans and will aid medical professionals in proper bite identification/treatment, potentially reducing bite misdiagnoses.

    First branchial cleft anomalies (FBCA) represent a small subset of congenital malformations in neck. Prime objective of this study is to share our experience with FBCA, emphasize its relevance in otolaryngology and deal with its pediatric perspective. Embryology, pathologic anatomy and varied spectra of clinical presentations of FBCA are discussed. Along with this we have illustrated three different cases; all of them were of pediatric age group and were misdiagnosed by their treating specialists elsewhere. In this article we have also laid special emphasis on its pediatric considerations. FBCA are mostly misdiagnosed due to their unfamiliar clinical signs and symptoms. Swellings may masquerade as other neck masses. Majority of patients give a history of previous incision and drainage. While dealing with pediatric patients the important factors to be kept in mind are the age of child, superficial course of facial nerve, any associated agenesis of parotid gland. Alteration in surgical technique may be required in children. A thorough medical examination with high index of clinical suspicion should be kept in mind while dealing with such anomalies. Owing to their complex presentation and close relation with facial nerve they are challenging lesions for surgeons.

  10. Imaging findings of mimickers of hepatocellular carcinoma

    Radiological imaging plays a crucial role in the diagnosis of hepatocellular carcinoma (HCC) as the noninvasive diagnosis of HCC in high-risk patients by typical imaging findings alone is widely adopted in major practice guidelines for HCC. While imaging techniques have markedly improved in detecting small liver lesions, they often detect incidental benign liver lesions and non-hepatocellular malignancy that can be misdiagnosed as HCC. The most common mimicker of HCC in cirrhotic liver is nontumorous arterioportal shunts that are seen as focal hypervascular liver lesions on dynamic contrast-enhanced cross-sectional imaging. Rapidly enhancing hemangiomas can be easily misdiagnosed as HCC especially on MR imaging with liver-specific contrast agent. Focal inflammatory liver lesions mimic HCC by demonstrating arterial-phase hypervascularity and subsequent washout on dynamic contrast-enhanced imaging. It is important to recognize the suggestive imaging findings for intrahepatic cholangiocarcinoma (CC) as the management of CC is largely different from that of HCC. There are other benign mimickers of HCC such as angiomyolipomas and focal nodular hyperplasia-like nodules. Recognition of their typical imaging findings can reduce false-positive HCC diagnosis.

    Cerebrovascular accidents, or strokes, and gliomas are common intraaxial brain lesions in dogs. An accurate differentiation of these two lesions is necessary for prognosis and treatment decisions. The magnetic resonance (MR) imaging characteristics of 21 dogs with a presumed cerebrovascular accident and 17 with a glioma were compared. MR imaging findings were reviewed retrospectively by three observers unaware of the final diagnosis. Statistically significant differences between the appearance of gliomas and cerebrovascular accidents were identified based on lesion location, size, mass effect, perilesional edema, and appearance of the apparent diffusion coefficient map. Gliomas were predominantly located in the cerebrum (76%) compared with presumed cerebrovascular accidents that were located mainly in the cerebellum, thalamus, caudate nucleus, midbrain, and brainstem (76%). Gliomas were significantly larger compared with presumed cerebrovascular accidents and more commonly associated with mass effect and perilesional edema. Wedge-shaped lesions were seen only in 19% of presumed cerebrovascular accidents. Between the three observers, 10-47% of the presumed cerebrovascular accidents were misdiagnosed as gliomas, and 0-12% of the gliomas were misdiagnosed as cerebrovascular accidents. Diffusion weighted imaging increased the accuracy of the diagnosis for both lesions. Agreement between observers was moderate (kappa = 0.48, P < 0.01).

    To describe cytology patterns in low-grade adenosquamous carcinomas (LGASCs) of the breast. Low-grade adenosquamous carcinomas of the breast are a recently described rare variant of primary metaplastic carcinomas characterized by clinical indolence, slow evolution and excellent survival. To date, only 7 cases of LGASC were studied cytologically, and it was demonstrated that LGASC identification was difficult because its cellular components exhibited unspecific and nonsuspicious features. They consisted of irregularly clustered cells without prominent cytonuclear atypia, mitosis or necrosis. The presence of metaplastic cells or keratin debris was helpful in accurate tumor typing. We report here 3 additional cases of LGASC that were initially studied by fine-needle aspiration. We have also encountered diagnostic difficulties and misdiagnosed tumors, since 2 cases were underdiagnosed as 'suspicious' and only 1 was accurately diagnosed as malignancy. The review of our cases and the literature confirms that, despite its putative metaplastic origin, LGASC is an entity which is difficult to diagnose using classical cytological methods. Moreover, core-needle biopsy as well as frozen sections may also misdiagnose LGASC as a benign breast lesion. © 2014 S. Karger AG, Basel.

    A total of 51 women with urinary schistosomiasis haematobium were examined in order to identify diagnostic indicators for female genital schistosomiasis (FGS). Patients were selected at random from the outpatient department of the Mangochi District Hospital, Malawi. The medical histories were recorded according to a pre-designed questionnaire and the women were subjected to a thorough gynaecological examination including colposcopy and photographic documentation of lesions. Microscopy of genital biopsies revealed that 33 of the 51 women had S. haematobium ova in cervix, vagina and/or vulva in addition to the presence of ova in urine. The most sensitive diagnostic procedure was beside microscopic examination of a wet cervix biopsy crushed between two glass slides, which revealed 25 of the 33 genital infections. There was a significant correlation between the size of genital lesions and the number of ova counted per mm2 of crushed tissue. Women with FGS had significantly more tumours in the vulva than women with schistosomiasis limited to the urinary tract. Most of the observed genital pathology could easily be identified by the naked eye, but colposcopic examination yielded valuable additional information like the demonstration of neovascularisation around cervical sandy patches. Few of the symptoms previously regarded as indicators for FGS could be linked to the presence of schistosome ova in genital tissue. Husbands of infertile women with FGS had children with other women significantly more often than husbands of women who only had urinary schistosomiasis. This, together with the finding that the majority of the divorced women had FGS, indicates that the manifestation of this disease may have implications for the marital and sexual life of the affected women.

    The objective of this descriptive study was to quantify the personal hygiene habits/practices of, as well as the over-the-counter (OTC) products used by, postmenopausal women. Specifically, we were interested in any product that would contact the vulva or vagina. We performed a cross-sectional study of postmenopausal women seeking routine gynecologic care. We developed a questionnaire on their personal hygiene habits/practices and the OTC products that they use that would contact the vulva or vagina. We recruited postmenopausal women seeking gynecologic care from two separate gynecology practices. Descriptive statistics were performed as appropriate to characterize the frequency of reported treatments and practices. The questionnaire on OTC treatments and perineal hygiene was completed by 114 postmenopausal women. Fifty-eight women (50.9%) reported using at least one OTC vulvovaginal treatment in the last 3 months, including barrier treatments, topical anesthetics, powders, and antifungals. Women often used more than one OTC product. Thirty-seven women (32.5%) reported the use of two or more OTC products. Powders were used by 34 women (29.8%). Talcum powder was the most commonly used powder (26 of 34; 76.5%). Nine postmenopausal women (7.9%) reported douching in the last 3 months. We found that more than half of postmenopausal women seeking gynecologic care have used an OTC product for vulvovaginal symptoms in the last 3 months and that one third of women use two or more products. Because the use of OTC products is very common, our study highlights the need for a detailed history inquiry about OTC product use and perineal hygiene practices.

    Covalent attachment of ubiquitin to substrate proteins changes their function or marks them for proteolysis, and the specificity of ubiquitin attachment is mediated by the numerous E3 ligases encoded by animals. Mind Bomb is an essential E3 ligase during Notch pathway signaling in insects and vertebrates. While Caenorhabditis elegans encodes a Mind Bomb homolog ( mib-1 ), it has never been recovered in the extensive Notch suppressor/enhancer screens that have identified numerous pathway components. Here, we show that C. elegans mib-1 null mutants have a spermatogenesis-defective phenotype that results in a heterogeneous mixture of arrested spermatocytes, defective spermatids, and motility-impaired spermatozoa. mib-1 mutants also have chromosome segregation defects during meiosis, molecular null mutants are intrinsically temperature-sensitive, and many mib-1 spermatids contain large amounts of tubulin. These phenotypic features are similar to the endogenous RNA intereference (RNAi) mutants, but mib-1 mutants do not affect RNAi. MIB-1 protein is expressed throughout the germ line with peak expression in spermatocytes followed by segregation into the residual body during spermatid formation. C. elegans mib-1 expression, while upregulated during spermatogenesis, also occurs somatically, including in vulva precursor cells. Here, we show that mib-1 mutants suppress both lin-12 and glp-1 ( C. elegans Notch) gain-of-function mutants, restoring anchor cell formation and a functional vulva to the former and partly restoring oocyte production to the latter. However, suppressed hermaphrodites are only observed when grown at 25°, and they are self-sterile. This probably explains why mib-1 was not previously recovered as a Notch pathway component in suppressor/enhancer selection experiments. Copyright © 2018 by the Genetics Society of America.

    Interdural hematomas are primarily observed in infants, and adult interdural hematomas are rare. We describe a 54-year-old woman with a round, well-defined mass. The mass was an interdural hematoma that was misdiagnosed as an epidural hematoma. Unlike an epidural hematoma, interdural hematomas are located between the two layers of the dura mater, and the dural tail sign can be observed. PMID:28664008

    A middle-aged man had deteriorated rapidly in hospital after being misdiagnosed with acute alcoholic hepatitis. Acute Legionnaires disease (Legionellosis) was subsequently diagnosed on rapid antigen urinary testing and further confirmed serologically. This led to appropriate antibiotic treatment and complete clinical resolution. Physicians caring for patients with alcohol-related liver disease should consider Legionella pneumophila in their differential diagnosis even with a paucity of respiratory symptoms.

    Autoimmune pancreatitis is a chronic inflammatory disorder that is often misdiagnosed as pancreatic cancer. Since autoimmune pancreatitis is benign and responds to steroid management, it is important to diagnose it to avoid unnecessary surgical intervention. We describe a novel case of IgG4-associated autoimmune pancreatitis presenting with tubulointerstitial nephritis as renal lesions mimicking metastatic tumours but with no change in renal function.
